ast-ksh package

+The AT&T Software Technology ast-ksh package from AT&T Research +contains ksh and support libraries. This is the minimal set of +components needed to build ksh. +Components in this package: +

+

+ + + +
+ksh93    libast    libcmd    libcoshell    libdll    libsum
+

+This package is a superset of the following package: ksh; you won't need this if you download ast-ksh. +The software is covered by this license: +

+Individual components may be covered by separate licenses; +refer to the component source and/or binaries for more information. +

+A recent +release change log +is also included. +

ksh93

+KSH-93 is the most recent version of the KornShell Language +described in +"The KornShell Command and Programming Language," +by Morris Bolsky and David Korn of AT&T Bell Laboratories, ISBN 0-13-182700-6. +The KornShell is a shell programming language, +which is upward compatible with "sh" (the Bourne Shell), +and is intended to conform to the IEEE P1003.2/ISO 9945.2 Shell and +Utilities standard. +KSH-93 provides an enhanced programming environment in +addition to the major command-entry features of the BSD +shell "csh". With KSH-93, medium-sized programming tasks can be +performed at shell-level without a significant loss in performance. +In addition, "sh" scripts can be run on KSH-93 without modification. +

+The code should conform to the IEEE POSIX 1003.1 standard and to the +proposed ANSI-C standard so that it should be portable to all +such systems. Like the previous version, KSH-88, +it is designed to accept eight bit character sets +transparently, thereby making it internationally compatible. +It can support multi-byte characters sets with some characteristics +of the character set given at run time. +

+KSH-93 provides the following features, many of which were also inherent +in KSH-88: +

    +
  • +Enhanced Command Re-entry Capability: The KSH-93 history +function records commands entered at any shell level and stores +them, up to a user-specified limit, even after you log off. +This allows you to re-enter long commands with a few keystrokes +- even those commands you entered yesterday. +The history file allows for eight bit characters in +commands and supports essentially unlimited size histories. +
  • +In-line Editing: In "sh", the only way to fix mistyped +commands is to backspace or retype the line. KSH-93 allows you +to edit a command line using a choice of EMACS-TC or "vi" +functions. +You can use the in-line editors to complete filenames as +you type them. +You may also use this editing feature when entering +command lines from your history file. +A user can capture keystrokes and rebind keys to customize the +editing interface. +
  • +Extended I/O Capabilities: KSH-93 provides several I/O +capabilities not available in "sh", including the ability to: +
      +
    • +specify a file descriptor for input and output +
    • +start up and run co-processes +
    • +produce a prompt at the terminal before a read +
    • +easily format and interpret responses to a menu +
    • +echo lines exactly as output without escape processing +
    • +format output using printf formats. +
    • +read and echo lines ending in "\". +
    +
  • +Improved performance: KSH-93 executes many scripts faster +than the System V Bourne shell. A major reason for this is +that many of the standard utilities are built-in. +To reduce the time to initiate a command, KSH-93 allows +commands to be added as built-ins at run time +on systems that support dynamic loading such as System V Release 4. +
  • +Arithmetic: KSH-93 allows you to do integer arithmetic in any +base from two to sixty-four. You can also do double +precision floating point arithmetic. +Almost the complete set of C language operators are available +with the same syntax and precedence. +Arithmetic expressions can be used to as an argument expansion +or as a separate command. +In addition there is an arithmetic for command that works +like the for statement in C. +
  • +Arrays: KSH-93 supports both indexed and associative arrays. +The subscript for an indexed array is an arithmetic expression, +whereas, the subscript for an associative array is a string. +
  • +Shell Functions and Aliases: Two mechanisms - functions and +aliases - can be used to assign a user-selected identifier to +an existing command or shell script. +Functions allow local variables and provide scoping +for exception handling. +Functions can be searched for and loaded on first reference the +way scripts are. +
  • +Substring Capabilities: KSH-93 allows you to create a +substring of any given string either by specifying the starting +offset and length, or by stripping off leading +or trailing substrings during parameter substitution. +You can also specify attributes, such as upper and lower case, +field width, and justification to shell variables. +
  • +More pattern matching capabilities: KSH-93 allows you to specify +extended regular expressions for file and string matches. +
  • +KSH-93 uses a hierarchal name space for variables. +Compound variables can be defined and variables can +be passed by reference. In addition, each variable +can have one or more disciplines associated with +it to intercept assignments and references. +
  • +Improved debugging: KSH-93 can generate line numbers on execution +traces. Also, I/O redirections are now traced. +There is a DEBUG trap that gets evaluated before each command +so that errors can be localized. +
  • +Job Control: On systems that support job control, including +System V Release 4, KSH-93 +provides a job-control mechanism almost identical to that of +the BSD "csh", version 4.1. +This feature allows you +to stop and restart programs, and to move programs between the +foreground and the background. +
  • +Added security: +KSH-93 can execute scripts which do not have read permission +and scripts which have the setuid and/or setgid set when +invoked by name, rather than as an argument to the shell. +It is possible to log or control the execution of setuid and/or +setgid scripts. +The noclobber option prevents you from accidentally erasing +a file by redirecting to an existing file. +
  • +KSH-93 can be extended by adding built-in commands at run time. +In addition, KSH-93 can be used as a library that can +be embedded into an application to allow scripting. +
+Documentation for KSH-93 consists of an "Introduction to KSH-93", +"Compatibility with the Bourne Shell" and a manual page and a +README file. In addition, the "New KornShell Command and Programming +Language," book is available from Prentice Hall. + +

+	  variables.
+10-11-29  An incorrect warning message was eliminated with the -n option for
+	  arithmetic expressions with associative arrays.

+	  now outputs an error message and returns value 126.
+10-06-23  Floating point functions that happened to return integer values
+	  were being treated as if the function returned integers so that
+	  integer division could be used instead of floating point division.
+10-06-22  Fixed a bug in earlier ksh93u in which an arithmetic assignment to a
+	  variable in the global scope would instead create a local variable if
+	  the variable had an attribute but did not have a value.

+	  executing the handler, it is deferred until the handler completes.
+10-06-16  Fixed a bug in which ulimit -v was setting the the cpu limit

+	  are not in the namespace are not modified when running command.
+10-06-07  Change most internal interfaces to take Sh_t* argument.
+10-06-03 +Types can be loaded on first reference by putting definitions in

+10-05-21  A bug in which using $var inside ((...)) did not work when var was
+	  a hex float variable.
+10-05-20 +The compile option SHOPT_EDPREDICT has been added.  When this option
+	  is on, as you type a line beginning with a # the following characters
+	  are treated as a shell pattern and cause matching lines from the
+	  history file to be displayed as a numbered list as you type.
+	  You can scroll up and down this list or you can use <ESC>nTAB
+	  to make this the current line (n defaults to 1 of omitted) or
+	  <ESC>n<cr> to execute.
+10-05-20  A bug which caused an exception when multiple levels of composite
+	  functions in arithemtic expressions has been fixed.

+10-04-29 +When the current job pool is set, coprocess are run in a job pool.
+10-04-28  A type defined with a member foo that is an associative array without
+	  elements followed by an expansion ${bar.foo[a]} and an assignment
+	  bar.foo[a]=b, no longer indicates that ${#bar.foo[@]} has 0 members.

+	  the subshell completed has been fixed.
+10-04-23  For file completion in commmand line editing, file names starting
+	  with # are now escaped so that they are not treated as comments.
+10-04-23  A bug in which ${t.var:=value}, where t is an instance of a type
+	  variable, could assign value to the type variable rather than to
+	  the type instance has been fixed.

+	  pipeline executed in the pool.
+10-04-22 +The .sh.pool variable was added for use with job pools.

+	  fail to compile with shcomp has been fixed.
+10-04-15 +Job pools have been added with the SHOPT_COSHELL compilation option.
+	  A job pool allows a collection of background jobs to run either locally 
+	  or remotely and to be managed as a unit.  The command '& name ...'
+	  creates or uses a named job pool for subsequent background jobs.
+	  kill, wait, and jobs allow the pool name as operands.
+10-04-14  A bug in which a coprocess connection could terminate prematurely
+	  when running a nested subshell has been fixed.
+10-04-12 +Enumeration constants can be used in arithmetic expressions with the

+	  'function .sh.math.name x y z{...}' , where name is the function name
+	  invoked within ((...)) and x y z are long double arguments passed
+	  as name references.  y and z are used for functions with two and
+	  three arguments respectively.  The value of the function is the value
+	  of the long double .sh.value variable when the function returns.

+	  numerator was a binary operator with the first operand floating
+	  point and the second integer, e.g. (.1**3)/3, has been fixed.

+	  fixed.
+10-03-19  Removed space between Stopped message and (SIGTTIN) and (SIGTTOUT).
+10-03-17  Modified profile shell execution so that when builtins that
+	  correspond to executable have extended attributes, they are
+	  executed by pfksh instead of being treated as built-ins.
+10-03-16  A bug in whence -a which produced duplicate lines of output has
+	  been fixed.
+10-03-16  A bug in the handling of process groups in monitor mode for

+	  been fixed.
+08-05-07 +The typeset -S option was added for variables outside type

+07-07-09  A bug in which typeset -a did not list indexed arrays has been
+	  fixed.
+07-07-03 +The command substitution ${ command;} has been added.  It behaves

+	  with a redirection and not occurring with in the while, until, if,
+	  select condition can be preceded by a semi-colon which will
+	  be ignored when showme is off.  When showme is on, any command
+	  preceded by a colon will be traced but not executed.
+06-08-16 +As a new feature, a leading ~(N) on a pattern has no effect 
+	  except when used for file expansion.  In this case if not
+	  matches are found, the pattern is replaced by nothing rather
+	  than itself.
+06-08-11  A bug in the expansion of ${.sh.match[i]:${#.shmatch[i]}} has
+	  been fixed.
+06-08-10 +The read builtin options -n and -N have been modified to treat
+          the size as characters rather than bytes unless storing into a
+	  binary (typeset -B) variable.
+06-07-27 +When the here document operator << is followed directly by a #
+	  rather than a -, the first line of the here-document determines
+	  how much whitespace is removed for each line.
+06-07-26  A bug in the C-shell history (enabled with set -H) in which the
+	  history event !$ was not processed has been fixed.
+06-07-21  A bug on some systems in which assigning PATH on a command line
+	  would not take effect has been fixed.
+06-07-20  Add ksh93 and rksh93 as allowable names for ksh binaries.
+06-07-20  Removed the SHOPT_OO compilation option which was only partially
+	  implemented.
+06-07-20  The ability to use egrep, grep, and fgrep expressions within
+	  shell patterns has been documented.
+06-07-17  A bug with arithmetic command expressions for locales in which
+	  the comma is a thousands separator has been fixed. 
+06-07-13 +The default HISTSIZE was increased from 128 to 512.
+06-07-13  A multibyte problem with locales that use shift codes has been fixed.
+06-06-23  A number of bug fixes for command, file, and variable completion
+	  have been mode.
+06-06-20 +Floating point division by zero now yields the constant Inf or -Inf
+	  and floating functions with invalid arguments yield NaN. 
+06-06-20 +The floating point constants Inf and NaN can be used in arithmetic
+	  expressions.
+06-06-20 +The functions isinf(), isnan(), tanhl() have been added for
+	  arithmetic expressions.
+06-06-13  Internal change to use ordering for variables instead of hashing
+	  to speed up prefix matching.
+06-06-13  A window between fork/exec in which a signal could get lost
+	  and cause a program to hang has been eliminated
+06-06-13  A bug in edit completion with quoted strings has been fixed.
+06-06-07  The restricted options can now be enabled by set as well as on
+	  the command line.  Once set, it can not be disabled.
+06-06-04  Modified built-in binding so that for systems for which /bin
+          and /usr/bin are the same, a builtin bound to /bin will get
+	  selected when either /bin or /usr/bin is scanned.
+06-06-04 +Added literal-next character processing for emacs/gmacs mode. 
+	  This change is not compatible with earlier versions of ksh93
+          and ksh88 when the stty lnext is control-v.  The sequence
+	  escape-control-v will display the shell version.
+06-05-31 +Modified emacs and vi mode so that entering a TAB after a partial
+	  TAB completion, generates a listing of possible completions.
+	  After the second TAB, a number followed by a TAB will perform
+	  the completion with the corresponding item.
+06-05-19 +Modified arithmetic so that conversions to strings default to
+	  the maximum number of precision digits.
+06-05-16  Bug fixes for multibyte locales. 
+06-05-10  The =~ operator was added to [[...]] and  [[ string ~= ERE ]]
+	  is equivalent to [[ string == ~(E)ERE ]].
+06-04-25  A bug in the vi edit mode which could cause the shell to core dump
+	  when switching from emacs mode.
+06-04-17  A bug in which using LANG or LC_ in assignment lists with builtins
+	  did not restore the localed correctly has been fixed.
+06-04-04  A bug in which discipline functions could not be added to variables
+	  whose names started with .sh has been fixed.
+06-03-28 +The -s option to typeset was added to modify -i to indicate short
+	  integers.
+06-03-28  A bug in which variables assignment lists before functions
+	  defined with function name were not passed on the functions
+	  invoked by this function has been fixed. 
+06-03-28  A bug in which name references defined within a function defined
+	  with function  name could not be used with compound variables has
+	  been fixed.
+06-03-27  A bug in which read <&p (print >&p) would cause the coprocess input
+	  (output) pipe to close before reading from (after writing to)
+          it has been fixed.
+06-02-28  A bug in which stopping a job created with the hist builtin command
+	  would create a job that could not be restarted has been fixed.  
+
+06-01-24  --- Release ksh93r  ---
+06-01-24  A bug in which running commands with standard output closed would
+	  not work as expected has been fixed.
+06-01-23  A bug in which print -u<n> could fail when file descriptor <n> was
+	  open for writing has been fixed.
+06-01-19  The ?: arithmetic operator fixed to work when the operation after
+	  the colon was an assignment.
+05-12-24  A bug which could lead to a core dump when elements of a compound
+	  variable were array elements, i.e. foo=(bar=(1 2)), has been fixed.
+05-12-13  An arithmetic bug in which x+=y+=z was not working has been fixed. 
+05-12-13  An arithmetic bug in which x||y was returning x when x was non-zero
+	  rather than 1 has been fixed.
+05-12-07 +The aliases for integer and float have been changed to use attributes
+	  -li and -lE to handle long long and long double types.
+05-12-07 +The histexpand (-H) option has been added which allows C-shell
+	  style history expansions using the history character !.
+05-12-07 +The multiline option was added which changes that way the edit
+	  modes handle lines longer than the window width.  Instead of
+	  horizontal scrolling, multiple lines on the screen are used.
+05-12-05  The whence builtin now returns an absolute pathname when the
+          command is found in the current directory.
+05-11-29  A bug which caused ksh -c '[[ ! ((' to core dump rather than
+	  report a syntax error has been fixed.
+05-11-29  A bug when reading fixed length records into typeset -b variables
+	  which caused a zero byte to terminate the value has been fixed.
+05-11-22 +The ability to seek to an offset within a file has been added
+	  with the new I/O redirection operators, <#  and >#.  Currently,
+	  these redirection operators must be followed by ((expr))
+	  but in a future release, it should be able to used to seek forward
+	  to the specified shell pattern.  In addition $(n<#) expands to the
+	  current byte offset for file descriptor n.
+05-11-22 +The .sh.match array variable is now set after each [[ ... ]]
+	  pattern match.  Previously it was only set for substring matches.
+05-10-17  A bug in which the library path variable could be prefixed
+          with a directory when a .path file was not encountered in
+	  the directory of the executable has been fixed.
+05-09-15  A for/while loop optimizer bug in which $OPTIND was not
+	  correctly expanded has been fixed.
+05-09-05  A bug in which a history command that invoked a history
+	  command could go into an infinite loop has been fixed.
+05-08-31 +In the case that IFS contains to adjacent new-lines so that
+	  new-line is not treated as a space delimiter, only a single
+	  new-line is deleted at the end of a command substitution.
+05-08-19 +When a tilde substitution expands to the / directory and is
+	  followed by a /, it is replaced by the empty string.
+05-08-16  A bug in which n<&m did not synchronize m has been fixed.
+05-08-16  A bug in which process substitution  ( <() and >() ) was not
+	  working within for and while loops has been fixed.
+05-07-24  A bug in which the pattern ~(E)(foo|bar) was treated as a syntax
+	  error has been fixed.
+05-07-24  A bug in completion with <n>=, where n was the one of the
+	  previous selection choices has been fixed.
+05-07-21  A bug with multibyte input when no edit mode was specified which
+	  caused the input line to shift left/right has been fixed.
+05-06-24  A race condition which could cause the exit status to get lost
+	  on some fast systems has been fixed.
+05-06-21  A bug in which nested patterns of the form {m,n}(pat) would cause
+	  syntax errors has been fixed.
+05-06-21  A bug in the macro expander has been fixed which could cause a
+          syntax error for an expansion of the form ${x-$(...)} when
+	  x is set and the command substitution contained certain strings.
+05-06-08 +On systems for which echo does not do System V style  expansions,
+	  the -e option was added to enable these expansion.
+05-06-08  A bug in which ${var op pattern} to not work when inside an
+	  arithmetic expression has been fixed.
+05-05-23 +An extension to shell patterns that allows matching of nested
+	  groups while skipping over quoted strings has been added.
+05-05-18  A bug in which the line number for errors was not correct for
+          functions loaded from FPATH has been fixed.
+05-04-18  A bug in which the exit status $? is not set when a trap triggered
+	  by the [[...]] command is executed has been fixed.
+05-04-08 +Redirection operators can be directly preceded with {varname}
+	  with no intervening space, where varname is a variable name which
+	  allows the shell to select a file descriptor > 10 and store it
+	  into varname.
+05-04-08 +SHOPT_CMDLIB_BLTIN=1 now includes <cmdlist.h> generated table.
+05-04-07 +[[ -o ?option ]] is true if "option" is a supported option.
+05-04-05  A bug in handling file completion with spaces in the names
+          has been fixed.
+05-03-25 +The SIGWINCH signal is caught by default to keeps the LINES and
+	  COLUMNS variables in sync with the actual window size.
+05-03-25 +Building ksh with SHOPT_REMOTE=1 causes ksh to set --rc if stdin is
+	  a socket (presumably part of a remote shell invocation.)
+05-03-25 +Building ksh with SHOPT_SYSRC=1 causes interactive ksh to source
+	  /etc/ksh.kshrc (if it exists) before sourcing the $ENV file.
+05-03-25 +{first..last[..incr][%fmt]} sequences added to brace expansions
+	  when braceexpand is enabled.
+05-03-03  A bug where a SIGCHLD interrupt could cause a fifo open to fail has
+	  been fixed.
+05-02-25  A bug in which a builtin command run in the background could
+	  keep a file descriptor open which could cause a foreground
+	  process to hang has been fixed.
+05-02-24  A bug where builtin library commands (e.g., date and TZ) failed to
+	  detect environment variable changes has been fixed.
+05-02-22 +The read builtin and word splitting are now consistent with respect
+	  to IFS -- both treat IFS as field delimiters.
+05-02-22 +The read builtin no longer strips off trailing delimiters that
+	  are not space characters when there are fewer variables than fields.
+05-02-17  A builtin bug on systems where dlsym(libcmd) returns link-time
+	  bindings has been fixed.
+05-02-12  A bug in which the lib_init() function for .paths BUILTIN_LIB
+	  libraries was not called has been fixed.
+05-02-06  A bug on some systems in which moving the write end of a co-process
+	  to a numbered file descriptor could cause it to close has been fixed. 
+05-02-06  A bug in the vi-edit mode in which the character under the cursor
+	  was not deleted in some cases with the d% directive has been fixed.
+05-02-06  A bug where external builtin stdout/stderr redirection corrupted
+          stdout has been fixed.
+05-02-04  A bug where times formatting assumed CLK_TCK==60 has been fixed.
+
+05-01-11  --- Release ksh93q  ---
+05-01-11  A bug in the integral divide by zero check has been fixed.
+05-01-11 +The -l option has been added to read /etc/profile and
+	  $HOME/.profile, if they exist, before the first command.
+05-01-11  An argument parsing bug that caused `kill -s x -- n' to fail has
+	  been fixed.
+05-01-11 +The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form 'BUILTIN_LIB=.'
+	  When a command is searched for this directory, and the full path
+	  matches the path of the built-in version of the command (listed
+	  by the 'builtin' command) then the built-in version of the command
+	  is used.  When ksh is built with SHOPT_CMDLIB_DIR=1 then all libcmd
+	  functions become builtins with the '/opt/ast/bin/' directory prefix.
+05-01-10  A bug in which a nameref to a compound name caused a core dump has
+	  been fixed.
+05-01-09  A bug in which some SIGCHLD interrupts (from child processes exiting)
+	  caused a fatal print/echo error diagnostic has been fixed.
+04-12-24  A bug in which some SIGCHLD interrupts (from child processes exiting)
+          corrupted the internal process/job list, sometimes causing the shell
+	  to hang, has been fixed.
+04-12-01  A bug in which typeset -Fn truncated less than n digits for large
+	  numbers has been fixed.
+04-11-25  A bug in which standard error could be closed after a redirection
+	  to /dev/stderr has been fixed.
+04-11-17  A bug in which an expansion of the form ${array[@]:3} could expand
+          to ${array[0]} when ${array[3]} was not set has been fixed.
+04-10-22 +The -E or -orc command line option reads ${ENV-$HOME/.kshrc} file.
+04-10-22 +`-o foo' equivalent to `+o nofoo', `-o nobar' equivalent to `+o bar'.
+          `--foo' equivalent to `-o foo', `--nofoo' equivalent to `+o foo'
+04-10-05 +The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form
+	  'BUILTIN_LIB=libname'.  When a command is searched for this directory,
+	  the shared library named by libname will first be searched for a
+	  built-in version of the command.
+04-09-03  <<< here documents now handle quotes in the word token correctly. 
+04-08-08 +The maximum size for read -n and and read -N was increased from
+	  4095 to 32M.
+04-08-04 +printf %q was modified so that if an no operand was supplied, no
+	  no output would be generated rather than a quoted empty string.
+04-08-01 +The -n and -N options of the read builtin has been modified
+	  when reading variables with the binary attribute so that the
+	  data is stored directly rather than through assignment.
+04-08-01 +The shcomp command has been modified to process alias commands
+	  under some conditions.
+04-07-31 +The .sh.match variable added in ksh93l, now works like other
+	  indexed arrays.
+04-07-08  A loop optimizer bug which occurs when typeset is used in
+	  a for or while loop inside a function has been fixed.
+04-06-24 +The number of subexpressions in a pattern was increased to 64
+	  from the current number of 20.
+04-06-17 +The -t option to read was modified to allow seconds to be
+	  specified as any arithmetic expression rather than just
+	  an integral number of seconds, for example even -t 'sin(.5)'
+	  is now valid.
+04-06-16  Two small memory leak problems were fixed.
+04-06-15  A bug in ${var/pattern/"string"} which occurred when string
+	  contained pattern matching characters has been fixed.
+04-05-08  printf $'%d produced an erroneous error message and has
+	  been fixed.
+04-05-24  A bug in which an associative array without any elements could
+	  cause a core dump when a script with an associative array with
+	  the same name was declared in a script invoked by name has
+	  been fixed.
+04-05-11  A bug in which an exec statement could close the script that
+	  is being processed in a script that is run by name causing
+	  a failure has been fixed.
+04-04-28 +If the first character of assignment to an integer variable was 0,
+          the variable had been treated as unsigned.  This behavior was
+          undocumented and has been removed.
+04-04-05  A bug in which the positioning of standard input could be incorrect
+	  after reading from standard input from a subshell has been fixed.
+04-03-30  A bug in the for loop optimizer which in rare cases could cause
+	  memory corruption has been fixed.
+04-03-29 +The preset alias source='command .' has been added.
+04-03-29  A bug introduced in ksh93p on some systems in which invoked by
+	  name with #! on the first line would not get the signals handling
+	  initialized correctly has been fixed. 
+04-03-29  A bug introduced in ksh93p in which a HUP signal received by
+	  a shell that is a session group leader was not passed down to
+	  its children has been fixed.
+
+04-02-28  --- Release ksh93p  ---
+04-02-28 +The ability to apply an append discipline to any variable has
+	  been added.
+04-02-14  A bug in which the exportall option (set -a) would cause incorrect
+	  results for arrays has been fixed.
+04-02-02  A bug in which an exported array would pass more than
+	  the first element to a script invoked by name has been fixed.
+04-02-02  A bug on some systems in which name=value pairs preceding a script
+	  invoked by name was not getting passed to the script has been fixed.
+04-01-20  A bug in which an unset discipline function could cause a core
+	  dump on some systems has been fixed.
+04-01-12  A bug in which a continue or break called outside a loop from
+	  inside a function defined with name() syntax could affect 
+	  the invoking function has been fixed.
+04-01-08  If a command name begins with ~, only filename completion will be
+	  attempted rather than pathname completion using the builtin editors. 
+04-01-08  A bug in the vi edit mode in which the wrong repeat count on
+	  multiple word replacements with the . directive has been fixed.
+04-01-06  Backspace characters are now handled correctly in prompt strings.
+04-01-06 +The getopts builtin has been modified to accept numerical
+	  arguments of size long long on systems that support this.
+04-01-06  A bug in which unsetting all elements of an associative array
+	  would cause it to be treated as an indexed array has been fixed.
+03-12-15  A bug in which a quoted string ending with an unescaped $ would
+	  delete the ending $ in certain cases has been fixed.
+03-12-05  A bug in which the shell could hang when set -x tracing a command
+	  when an invalid multibyte character is encountered has been fixed. 
+03-12-05  On some systems, if the KEYBD trap is set, then commands that use
+	  the meta key were not processed until return was hit.  This
+	  has been fixed.
+03-12-05  A problem which occurred when the login shell was not a group
+	  leader that could cause it to fail has been fixed.
+03-12-05  A problem in which a shell could core dump after receiving a signal
+	  that should cause it to terminate while it was in the process
+	  of acquiring more space has been fixed.
+03-12-05 +If ENV is not specified, the shell will default to $HOME/.kshrc
+	  for interactive shells.
+03-11-21  A bug introduced in ksh93o in which the DEBUG trap could get
+	  disabled after it triggered has been fixed. 
+03-11-04  A bug in which using arithmetic prefix operators ++ or -- on a
+	  non-lvalue could cause a core dump has been fixed.
+03-11-04  A bug in which leading zeros were stripped from variable
+	  expansions within arithmetic computation to avoid being treated
+	  as octal constants when they should not have, has been fixed.
+03-10-08  A bug introduced in ksh93o in which a large here document inside
+	  a function definition could get corrupted has been fixed.
+03-09-22  A bug in which the .get discipline function was not being
+	  called when a string variable was implicitly referenced from
+	  within a numerical expression has been fixed.
+03-09-22  A bug in which a script without a leading #! could get executed
+	  by /bin/sh rather than the current shell on some systems has
+	  been fixed.
+03-09-12 +To improve conformance with ksh88, leading zeros will be ignored
+	  when getting the numerical value of a string variable so that
+	  they will not be treated as octal constants.
+03-09-03 +The builtin kill command now processes obsolete invocations
+	  such as kill -1 -pid.
+03-09-02  The restriction on modifying FPATH in a restricted shell (sh -r)
+	  has been documented.
+03-09-02 +The restricted shell (sh -r) has been modified to disallow
+	  executing command -p.
+03-08-07  A bug in which the KEYBD trap was not being invoked when
+	  characters with the 8th bit set has been fixed.
+03-08-02  A parser bug introduced in ksh93o which caused the character
+	  after () in a Posix function definition to be skipped 
+	  when reading from standard input has been fixed.
+03-08-01  A bug in which "${foo#pattern}(x)" treated (x) as if it were
+	  part of the pattern has been fixed.
+03-08-01 +The command -x option has been modified so that any trailing
+	  arguments that do expand to a single word will be included
+	  on each invocation, so that commands like command -x mv * dir
+	  work as expected.
+
+03-07-20  --- Release ksh93o+  ---
+03-07-20  A bug in which could cause memory corruption when a posix
+	  function invoked another one has been fixed.
+03-07-15  A bug in which a file descriptor>2 could be closed before
+	  executing a script has been fixed.
+03-07-15  A parsing error for <() and >() process substitutions inside
+	  command substitution has been fixed.
+03-07-15  A parsing error for patterns of the form {...}(...) when
+	  used inside ${...} has been fixed.
+03-07-15  An error in which expanding an indexed array inside a compound
+	  variable could cause a core dump has been fixed.
+03-07-15  A bug in which on rare occasions a job completion interrupt
+	  could cause to core dump has been fixed.
+03-06-26  A bug in which process substitution embedded within command
+	  substitution would generate a syntax error has been fixed.
+03-96-23  A bug in which ${@:offset:len} could core dump when there
+	  were no arguments has been fixed.
+03-96-23  A bug in which ${X[@]:offset:len} could core dump when X
+	  was unset has been fixed.
+03-06-22 +The -x option was added to the command builtin.  If this
+	  option is on, and the number of arguments would exceed ARG_MAX,
+	  the command will be invoked multiple times with a subset of
+	  the arguments.  For example, with alias grep='command -x grep,
+	  any number of arguments can be specified.
+03-06-14  A bug in which could cause a core dump on some systems with
+	  vi and emacs editors with the MULTIBYTE option has been fixed.
+03-06-06  A bug in which the shell could core dump when a script was
+	  run from its directory, and the script name a symlink to a file
+	  beginning with .., has been fixed.
+03-06-05  A bug in which the shell could core dump when a child process
+	  that it is unaware of terminates while it is calling malloc()
+	  has been fixed.
+03-06-02 +An option named globstar (set -G) has been added.  When enabled,
+	  during pathname expansion, any component that consists only of ** is
+	  matches all files and any number of directory levels.
+03-05-30  A bug in which the PATH search could give incorrect results when
+	  run from directory foo and PATH contained .:foo:xxx has been fixed.
+03-05-29 +Some changes were made to the code that displays the prompt in edit 
+	  mode to better handle escape sequences in the prompt.
+03-05-27  I added = to the list of characters that mark the beginning of
+	  a word for edit completion so that filenames in assignments
+	  can be completed.
+03-05-20  A bug in which read -N could hang on some systems when reading
+	  from a terminal or a pipe has been fixed.
+03-05-19  A bug in which the output of uname from a command substitution
+	  would go to the standard output of the invoking command when
+	  uname was invoked with a non-standard option has been fixed.
+03-05-19  A job control bug which would cause the shell to exit because 
+	  it hadn't take back the terminal has been fixed.  The bug
+	  could occur when running a function that contained a pipeline
+	  whose last element was a function.
+03-05-19  A job control timing bug introduced in ksh93o on some systems
+	  which could cause a pipeline to hang if the first component
+	  completed quickly has been fixed.
+03-05-13 +The read builtin has been modified so that the builtin editors
+	  will not overwrite output from a previous incomplete line. 
+03-05-13  A bug in which the name of an identifier could have the string
+	  .sh. prefixed to it after expanding a variable whose name begins
+	  with .sh. has been fixed.
+03-05-13  A bug in the expansion of $var for compound variables in which
+	  some elements would not be output when the name was a prefix
+	  of another name in the compound variable has been fixed.
+03-05-08  The last item in the ksh93o release on 03-01-02 has been
+	  altered slightly to preserve the leading 0's when the
+	  preceding character is a digit.  Thus, with typeset -LZ3 x=10,
+	  $(( 1$x)) will be 1010 whereas $(( $x) will be 10.
+03-04-25  A bug in which if x is a name reference, then nameref y=x.foo
+	  did not follow x has been fixed.
+
+03-03-18  --- Release ksh93o  ---
+03-03-18 +A -N unary operator was added to test and [[...]] which returns
+	  true if the file exists and the file has been modified since it
+	  was last read.
+03-03-18 +The TIMEFORMAT variable was added to control the format for
+	  the time compound command.  The formatting description is
+	  described in the man page.
+03-03-06 +A -N n option was added to read which causes exactly n bytes
+	  to be read unlike -n n which causes at most n bytes to be read.
+03-03-03 +Three new shell variables were added.  The variable .sh.file
+	  stores the full pathname of the file that the current command
+	  was found in.  The variable .sh.fun names the current function
+	  that is running.  The variable .sh.subshell contains the depth
+	  of the current subshell or command substitution.
+03-03-03 +When the DEBUG trap is executed, the current command line after
+	  expansions is placed in the variable .sh.command.  The trap
+	  is also now triggered before each iteration of a for, select,
+	  and case command and before each assignment and redirection.
+03-02-28 +Function definitions are no longer stored in the history file so
+	  that set -o nolog no longer has any meaning.
+03-02-28 +All function definitions can be displayed with typeset -f not
+	  just those stored in the history file.  In addition, typeset +f
+	  displays the function name followed by a comment containing the
+	  line number and the path name for the file that defined this function.
+03-02-28  A bug in which the value of $LINENO was not correct when executing
+	  command contained inside mult-line command substitutions has been
+	  fixed.
+03-02-19 +Since some existing ksh88 scripts use the undocumented and
+	  unintended ability to insert a : in front of the % and # parameter
+	  expansion operators, ksh93 was modified to accept :% as equivalent
+	  to % and :# as equivalent to # with ${name op word}.
+03-02-14  A bug which could cause a core dump when reading from standard
+	  error when standard error was a pty has been fixed.
+03-02-14 +The shell arithmetic was modified to use long double on systems
+	  that provide this data type.
+03-02-09  A bug in which a function located in the first directory in FPATH
+	  would not be found when the last component of PATH was . and the
+	  current directory was one of the directories in PATH has been fixed.
+03-02-07 +The trap and kill builtin commands now accept a leading SIG prefix
+	  on the signal names as documented.
+03-02-05  A bug in the expansion of ${var/$pattern}, when pattern contained
+	  \[ has been fixed.
+03-02-05  A bug in which .sh.match[n], n>0, was not being set for substring
+	  matches with % and %% has been fixed.
+03-01-15  A bug in which getopts did not work for numerical arguments specified
+	  as n#var in the getopts string has been fixed.
+03-01-09  A bug in which using ${.sh.match} multiple times could lead to
+	  a memory exception has been fixed.
+03-01-06  A bug in the expansion of ${var/pattern/$string} in the case that
+	  $string contains \digit has been fixed. 
+03-01-02 +A -P option was added for systems such as Solaris 8 that support
+	  profile shell.
+03-01-02  For backward compatibility with ksh88, arithmetic expansion
+	  with ((...)) and let has been modified so that if x is a zero-filled
+	  variable, $x will not be treated as an octal constant.
+
+02-12-05  --- Release ksh93n+  ---
+02-11-30  A bug that can show up in evaluating arithmetic statements that
+	  are in an autoloaded function when the function is autoload from
+	  another function has been fixed.
+02-11-30  An optimization bug in which an expansion of the form ${!name.@},
+	  which occurred inside a for or a while loop, when name is a name
+	  reference, has been fixed.
+02-11-18  A bug in which modifying array variables in a subshell could leave
+	  side effects in the parent shell environment has been fixed.
+02-11-18  A memory leak when unsetting an associative array has been fixed.
+02-11-14 +The code to display compound objects was rewritten to make
+	  it easier for runtime extensions to reuse this code.
+02-11-14 +A change was made to allow runtime builtins to be notified when
+	  a signal is received so that cleanup can be performed.
+02-10-31 +User applications can now trap the ALRM signal.  Previously,
+	  the ALRM signal was used internally and could not be used
+	  by applications. 
+02-10-31  A bug in which signals received while reading from a coprocess
+	  for which traps were set was not handled correctly has been fixed.
+02-10-31  A bug in which a file opened with exec inside a subshell could
+	  be closed before the subshell completed has been fixed.
+02-10-21  A bug in which setting PATH or FPATH inside a function might not
+	  take effect has been fixed.
+02-10-21  A bug which could cause a core dump when a local SECONDS variable
+	  is defined in a function has been fixed.
+02-10-15  A bug in which the associate array name operator ${!array[@]}
+	  could return the same name multiple times has been fixed.
+02-10-15  A bug in which the zero'th element of an associative array was
+	  not getting set when an assignment was made without a subscript
+	  specified has been fixed.
+
+02-09-30  --- Release ksh93n  ---
+02-09-30 +The maximum indexed array size was increased to 16Megs.
+02-09-30  A bug which could cause a core dump when changing attributes
+	  of associative array has been fixed.
+02-09-30  A bug in which exporting an array variable would not export the
+	  0-th element has been fixed.
+02-09-30  A bug in which an array assignment of the form a=($a ...) would unset
+	  'a' before the right hand side was evaluated has been fixed.
+02-09-27  A bug in which the error message for ${var?message} when var was
+	  null or unset did not contain the variable name var has been fixed.
+02-09-27  A bug in which closing file descriptors 0 through 2 could
+	  cause a subsequent here document to fail has been fixed. 
+02-09-14  A bug in whence which occurs when the specified name contained
+	  a / has been fixed.
+02-09-14  A bug in the parser for strings of the form name$((expr))=value
+	  has been fixed.
+02-09-14  A for loop optimization bug in which the number of elements in
+	  an array was treated as an invariant has been fixed.
+02-09-09  A bug in which redirection or closing of a file descriptor between
+	  3 and 9 could cause a subsequent here document to fail has been
+	  fixed. 
+02-09-09  A bug in which a background job was not removed from the job list
+	  when a subshell completed has been fixed, for example (prog&). 
+02-09-03  A bug in which an assignment of the form name=(integer x=3)
+	  could be interpreted as an array assignment rather than a
+	  compound variable assignment has been fixed.
+02-08-19  A command completion bug which occurred on file systems that
+	  are case insensitive has been fixed.
+02-08-19  A bug which could lead to an exception on some systems (for
+	  example FREEBSD) which occurred when setting PATH has been fixed.
+02-08-11  A bug in arithmetic rounding in which a value input as a decimal
+	  string would output as a rounded version of the string has
+	  been fixed.
+02-08-11  A bug in which the last character could be deleted from shell
+	  traces and from whence when called from a multibyte locale
+	  has been fixed.
+02-08-01  A bug which could cause a core dump to occur when a shell script
+	  is executed while a coprocess is running that has closed the
+	  output pipe has been fixed.
+02-08-01  A bug in which command completion in multibyte mode could
+	  corrupt memory for long command lines has been fixed.
+
+02-06-17  --- Release ksh93n-  ---
+02-06-17  A bug in which user defined macros could cause a core dump in
+	  with MULTIBYTE mode has been fixed.
+02-06-17  A bug in which printf format specifiers of the form %2$s were causing
+	  a core dump has been fixed.
+02-06-17  A bug in which setting stty to noecho mode did not prevent the
+	  echoing of characters by ksh when emacs or viraw mode
+	  was enabled has been fixed.
+02-06-17  A bug in which background job completion could cause the sleep
+	  builtin to terminate prematurely has been fixed.
+02-06-17  A bug in which the shell could core dump if getopts was called
+	  when the OPTIND variable contained a negative value has been fixed. 
+02-06-10 +The edit mode prompt has been modified to handle escape sequences.  
+02-06-10  A bug which occurred for interactive shells in which the builtin
+	  cat command was used in command substitution on a file whose
+	  size was larger than PIPE_BUF has been fixed.
+02-06-10  A bug in which the trap on ERR was not being processed when
+	  set inside a function has been fixed.
+02-06-07  A bug in which function definitions could cause the history count
+	  to be decremented by one (and even become negative) has been fixed.
+02-06-05  A bug in read in which share mode could be enabled has been fixed.
+02-05-28  A bug which could occur when the last command of a script was
+	  a case statement and the action selected ended in ;& instead of ;;
+	  has been fixed.
+02-05-23  A bug with unary + introduced in ksh93k has been fixed.
+02-05-07  A bug in substitutions of the form ${var/pattern/string} in which
+	  a backslash was inserted in the replacement string when it contained
+	  a special pattern character has been fixed.
+02-05-01  A bug in the emacs edit mode which occurred in versions compiled
+	  for multibyte character sets which occurred when a repeated search
+	  was requested after a long line had been returned for the previous
+	  search has been fixed.
+02-04-02 +vi and emacs edit modes were modified so that tab completion is
+	  disabled when invoked from the read built-in.
+
+02-03-26  --- Release ksh93m+  ---
+02-03-26  A bug in which  was not handled correctly when used in file
+	  expansion has been fixed.
+02-02-18  A bug in which lines beginning with a # were deleted from here
+	  documents when the here-document delimiter was followed by
+	  a comment has been fixed.
+02-12-06  An optimization bug in which ${!x[@]) was treated as invariant in
+	  a for loop has been fixed.
+02-02-06  A bug in which the ERR trap is not cleared for a script invoked
+	  by name from within a function has been fixed.
+02-01-08  A bug in which a shell script executed from within a subshell
+	  could cause this script to have an invalid pointer leading
+	  to a memory fault has been fixed. 
+02-01-07 +Added here documents of the form <<< word (as per zsh) which
+	  is equivalent to << delimordelim.
+02-01-07  A bug in which the first word of a compound assignment,
+	  x=(word ...), was treated as a reserved word has been fixed.
+02-01-07  A bug in the handling of  when noglob was enabled and a
+	  substitution of the form ${word op pattern} occurred in the
+	  same word has been fixed.
+02-01-07 +A compilation option, CMDLIB_BLTIN in the file OPTION, has
+	  been added.  When this options is set, all commands implemented
+	  in libcmd become shell builtin commands by default.
+02-01-07  A bug in which builtin foo, where foo is already a builtin
+	  would result in the builtin foo getting removed has been fixed. 
+02-01-07  A bug which the shell executed a command found in the current
+	  directory when PATH have no valid directories has been fixed.
+01-11-28  The value of $? was not being set when called with exit.
+01-11-28  If the last command was of the form (...) and a trap on EXIT or
+	  ERR was set, and the command inside () modified the trap, then
+	  the original trap wasn't executed.
+01-11-26 +The value for 0 is now preceded by the base number when
+	  the base was not 10.
+01-11-26 +The default has compilation mode has been changes so that
+	  viraw mode will always be on.
+
+01-10-31  --- Release ksh93m  ---
+01-10-31  A for loop optimizer bug for subshells contained withing for
+	  loops has been fixed.
+01-10-16  typeset without arguments no longer outputs variable names
+	  that do not have any attributes that are set.
+01-10-16  A bug introduced in ksh93l in which assignments specified with
+	  the exec built-in were not being expanded properly has been
+	  fixed.
+01-10-11  An optimization bug in which ${!x) was treated as invariant in
+	  a for loop has been fixed.
+01-10-11  Unsigned integer variables in bases other than 10 are printed now
+	  expand in that base with the base prefix.
+01-10-10  A number of typos in the self generating man pages for shell
+	  built-ins have been fixed.
+01-10-04  The self generated man pages for hist and fc were not working
+	  correctly and have been fixed.
+01-10-03  Yet another optimizer bug in which shell patterns were
+	  treated as invariants has been fixed.
+01-09-27  Two bugs relating to multibyte history searches and to find
+	  have been fixed.
+01-09-27  A bug introduced in ksh93k in which the PATH searching was
+	  not restored after running a command with an assignment list 
+	  has been fixed.
+01-09-26  A bug in which a zero filled field was treated as octal when
+	  converted to integer has been fixed.
+01-09-26  Yet another bug in the optimization of for loops related to
+	  recursive functions with break or continue statements has been fixed.
+01-09-25 +The exponentiation operator ** was added to the shell arithmetic
+	  evaluation.  It has higher precedence than * and is left
+	  associative.
+01-09-25  The code was modified to use the ast multibyte macros
+	  and functions for handing multibyte locales.
+01-09-25 +The expansion ${parameter:offset:length} now handles negative
+	  offsets which cause offsets to be measured from the end.
+01-09-25  Some spelling errors in the documentation were corrected.
+01-09-24 +The /dev/tcp/host/port and /dev/udp/host/port now allow
+	  the ports to be specified by service name. 
+01-09-24 +The change staring with ksh93g in which the the appropriate
+	  library path variable is prepended with a corresponding library
+	  directory has been modified.  With the new method, only the
+	  library path defined in the file named .paths in the directory
+	  where the executable is found will be modified.  See the
+	  man page for more details.
+01-09-23 +The .fpath file (see ksh93h) is no longer looked for in each
+	  directory on the path to locate function directories.  The
+	  file named .paths is used instead.
+01-09-23  A bug in which IFS was not being restored after being changed in
+	  a subshell has been fixed.
+01-09-16 +With the vi and emacs edit modes, after a list of command
+	  or functions is generated with = or M-= respectively,
+	  any element from the list can be pasted on the command line
+	  by preceding the = or M-= with a numeric parameter specifying
+	  the position on the list.
+01-09-16  A bug in ksh93l caused command completion not to find aliases
+	  and functions.  Command listing from the edit mode was presented
+	  in reverse order.  This has been fixed.
+01-09-13  Another bug in the optimization of for loops related to subshells
+	  when traps were set has been fixed.
+01-09-07  A change in ksh93l caused brace expansion to stop working
+	  and this has been fixed.
+01-09-04  A bug introduced in ksh93k in which an arithmetic statement
+	  within a function that used name references did not follow the
+	  reference has been fixed.
+01-09-04  A bug introduced in ksh93l in which export -p did not prefix
+	  each export with the word export has been fixed.
+01-08-29  A bug in multibyte input which occurred when a partial multibyte
+	  character was received has been fixed.
+01-08-29  A bug introduced in ksh93l which could cause a core dump
+	  when an assignment list containing PATH is specified inside
+	  command substitution has been fixed.
+01-08-09  Another bug in the optimization of for loops in ksh93l caused
+	  errors in recursive functions using local variables that
+	  contained for loops has been fixed.
+01-07-27  A bug in which IFS would be unset after a command substitution
+	  inside a here document has been fixed.
+01-07-26  To conform to the POSIX standard, if you invoked ksh name,
+	  and name does not contain a /,  it will first try to run
+	  one in the current directory whether it is executable or not
+	  before doing a path search for an executable script.  Earlier
+	  versions first checked for an executable script using the
+	  PATH variable.
+01-07-23  A bug in which unset -f invoked in a subshell could unset a
+	  function defined in the parent has been fixed.
+01-07-16  A bug in the optimization of for loops in ksh93l caused
+	  name references to be treated as invariants has been fixed.
+01-07-09  A bug in which a discipline function applied to a local variable
+	  could cause a shell exception has been fixed.  Discipline
+	  functions can only be specified for global variables. 
+
+01-06-18  --- Release ksh93l  ---
+01-06-18  A bug in assigning integers larger than can be represented as
+	  long integers to floating point variables has been fixed.
+01-06-18  A bug in the handling of unsigned integers (typeset -ui) has
+	  been fixed.
+01-06-04  The evaluation of the PS1 prompt no longer effects the value
+	  of the $? variable.
+01-06-01  A small memory leak from subshells has been fixed.
+01-05-22  A bug in which attributes for variables that did not have
+	  values would be lost after a subshell has been fixed.
+01-05-22 +The %R format has been added to convert a shell pattern into
+	  an extended regular expression.
+01-05-22 +The escape sequences \, X, \C[.collating-element.], and
+	  \x{hex} have been added to ASCII-C strings and to printf format
+	  strings.
+01-05-20 +Patterns of the form {n}(pattern) and {m,n}(pattern) are now
+	  recognized.  The first form matches exactly n of pattern whereas,
+	  the second form matches from m to n instances of pattern.
+01-05-20 +The shell allows *-(pattern), +-(pattern),  ?-(pattern),
+	  {m,n}-(pattern}, and @-(pattern) to cause the minimal
+	  match of pattern to be selected whenever possible rather
+	  than the maximal (greedy) match. 
+01-05-20 +The character class [:word:] has been added to patterns.
+	  The word class is the union of [:alnum:] and the character _.
+01-05-20 +Inside (...) pattern groups, the  character is now treated
+	  specially even when in an enclosing character class.  The
+	  sequences, \w, \d, \s are equivalent to the character classes
+	  word, digit, and space respectively.  The sequences \W, \D,
+	  and \S are their complement sets. 
+01-05-20 +The shell now recognizes pattern groups of the form
+	  ~(options:pattern) where options or :pattern can be omitted.
+	  Options use the letters + and - to enable and disable options
+	  respectively.  The option letters g (greedy), i (ignore case)
+	  are used to cause maximal matching and to cause case
+	  insensitive matching respectively.  If :pattern is also
+	  specified, these options are only in effect while this
+	  pattern is being processed.  Otherwise, these options remain
+	  in effect until the end of the pattern group that they are contained
+	  in or until another ~(...) is encountered.  These pattern groups
+	  are not counted with respect to group numbering.
+01-05-14  When edit completion, expansion, or listing occurs in the
+	  middle of a quoted string, the leading quote is ignored when
+	  performing the completion, expansion, or listing.
+01-05-14  A small memory leak from subshells has been fixed.
+01-05-10  A bug in which open files were not restored after a subshell
+	  that had used exec to replace a file has been fixed. 
+01-05-10 +Redirection to a null file name now generates an error message. 
+01-05-09  The shell now rejects some invalid parameter substitutions that
+	  were previously processed in undefined ways.
+01-05-09  A bug in which the output of select was not flushed before the
+	  read when input did not come from the terminal has been fixed. 
+01-05-08  A bug in which job ids would not be freed for interactive shells
+	  when subshells ran built-ins in the background has been fixed.
+01-05-08 +The FPATH variable now requires an explicit . to cause the
+	  current directory to be treated as a function directory. 
+01-05-08  A bug in read -n when echo mode was disabled has been fixed.
+01-05-07  A bug in which function definitions could be listed as part
+	  of the history has been fixed.
+01-04-30 +This release uses a new and often much faster pattern matcher than
+	  earlier releases.
+01-04-30 +An optimizer now eliminates invariant parameter expansions from
+	  for while and until loops.
+01-04-30 +The variable .sh.match is set after each pattern match (# % or /)
+	  in a variable substitution.  The variable .sh.match is an
+	  indexed array with element 0 being the complete match. 
+	  The array is only valid until the next subsequent pattern
+	  match or until the value of the variable changes which ever
+	  comes first.
+01-04-30 +A self generating man page has been added to shcomp.  Also,
+	  shcomp now stops compiling when it finds an exit or exec
+	  command and copies the remainder so that it can be used
+	  for standard input.
+01-04-30 +The shcomp command was modified so that it can work in an
+	  EBCIDIC environment and that binary scripts are portable
+	  across environments.
+01-04-30  A bug in the handling of a trailing : in PATH has been fixed.
+01-04-30  A bug in which the builtin version of a command would get invoked
+	  even though the full pathname for the command was specified
+	  has been fixed.
+01-04-30  A bug in which read would loose the last character when
+	  reading the last line of a file that did not contain a new-line
+	  character has been fixed.
+01-04-23  A bug on some systems in which in vi mode the end of file
+	  character and end of line character could be swapped has
+	  been fixed.
+01-04-23  A bug on some systems in which invoking a shell script that
+	  did not have execute permission could set the exit value to
+	  127 rather than 126 has been fixed.
+01-04-20  A bug in which read -n from a pipe would block if fewer than
+	  n characters was received has been fixed.
+01-04-09  A bug in which invalid patterns, for example, ) by itself,
+	  was not treated as a string has been fixed so that if i=')',
+	  then [[ $i == $i ]] is true.
+01-04-09 +The shell arithmetic now interprets C character constants.
+01-04-09  A bug in which a non-zero return from a function defined
+	  with the function reserved word did not trigger the ERR
+	  trap or exit with set -e has been fixed.
+01-04-02  A bug on some systems, in which characters above 127 were
+	  not displayed correctly in vi or emacs edit mode has been fixed.
+01-04-02  A bug on some systems, introduced in the 'k' point release, in
+	  which the erase character in viraw mode was moving the cursor
+	  to the left without erasing the character has been fixed.
+01-04-02  On some systems the wcwith() function was returning a wrong
+	  value for characters and caused characters to be displayed
+	  incorrectly from the shell edit modes.  A work around for
+	  this problem has been added. 
+01-03-26  A bug in which valid scripts could produce syntax errors
+	  when run with locales that considered characters such as "'"
+	  to be space characters has been fixed.
+01-03-20  A bug in which an syntax error in an arithmetic expression
+	  entered interactively could cause the shell to go into
+	  an infinite loop outputting the error message has been fixed.
+01-03-10 +ksh93 accepts -l as a synonym for -L in test on systems for
+	  which /bin/test -l tests for symbolic links.
+01-03-10  A bug in parsing scripts in which { and } are used in place of
+	  in and esac in case statements embedded in compound commands
+	  has been fixed.  Use of { and } for in and esac is obsolete.
+01-03-06  A bug in which an argument of the form foo=bar was not
+	  being passed correctly to a traced function whose name
+	  was foo has been fixed.
+01-03-02  Using $(trap -p name) did not print the name of the current
+	  trap setting for trap name.
+01-02-26  Exported floating point variables gave incorrect results
+	  when passing them to ksh88.  This has been fixed.
+01-02-25  A race condition in which a coprocess which completed too quickly
+	  would not allow subsequent coprocesses to start has been fixed.
+01-02-25  The 'g' format specifier is now handled by printf.  It had
+	  inadvertently been omitted.
+01-02-20  The + was not being displayed during an execution trace
+	  with the += assignment operator.
+01-02-19  The error message which occurs when the interpreter name
+	  defined on the #! line does not exist is more informative.
+01-02-19  A bug in which $0 would not be set correctly when a
+	  script with #! was invoked by full pathname from the
+	  directory of the script has been fixed.
+01-02-19  A shell script did not always pick up tty mode changes
+	  made by external commands such as stty which could
+	  effect the behavior of read.
+01-02-19  The -u, -g, and -k unary tests did not give the correct
+	  results when used with negation and this has been fixed.
+
+01-02-05  --- Release ksh93k+  ---
+01-02-05  The sequence \<newline> inside $'...' was not incrementing
+	  the line count and this has been fixed.
+01-02-05 +Modified expansion of "${@-}" so that if no arguments are set
+	  it results in null string rather than nothing.
+01-02-02  memory leak problem with local variables in functions fixed.
+01-01-25 +allow arithmetic expressions with float%int and treat them
+	  as ((int)float)%int rather than as an error. 
+01-01-19  read -n1 was not working and has been fixed.
+01-01-17 +ksh now handles the case in which a here document in command
+	  substitution $() is terminated by the trailing ).  Previously,
