Prepare nawk for use as a bootstrap tool by including the sources
directly in pkgsrc/lang/nawk/files and adjusting the package Makefile accordingly. The README.pkgsrc file includes notes on how the source files were (minimally) adjusted.

+****************************************************************/
+
+This file lists all bug fixes, changes, etc., made since the AWK book
+was sent to the printers in August, 1987.
+
+Apr 24, 2005:
+ modified lib.c so that values of $0 et al are preserved in the END
+ block, apparently as required by posix. thanks to havard eidnes
+ for the report and code.
+
+Jan 14, 2005:
+ fixed infinite loop in parsing, originally found by brian tsang.
+ thanks to arnold robbins for a suggestion that started me
+ rethinking it.
+
+Dec 31, 2004:
+ prevent overflow of -f array in main, head off potential error in
+ call of SYNTAX(), test malloc return in lib.c, all with thanks to
+ todd miller.
+
+Dec 22, 2004:
+ cranked up size of NCHARS; coverity thinks it can be overrun with
+ smaller size, and i think that's right. added some assertions to b.c
+ to catch places where it might overrun. the RE code is still fragile.
+
+Dec 5, 2004:
+ fixed a couple of overflow problems with ridiculous field numbers:
+ e.g., print $(2^32-1). thanks to ruslan ermilov, giorgos keramidas
+ and david o'brien at freebsd.org for patches. this really should
+ be re-done from scratch.
+
+Nov 21, 2004:
+ fixed another 25-year-old RE bug, in split. it's another failure
+ to (re-)initialize. thanks to steve fisher for spotting this and
+ providing a good test case.
+
+Nov 22, 2003:
+ fixed a bug in regular expressions that dates (so help me) from 1977;
+ it's been there from the beginning. an anchored longest match that
+ was longer than the number of states triggered a failure to initialize
+ the machine properly. many thanks to moinak ghosh for not only finding
+ this one but for providing a fix, in some of the most mysterious
+ code known to man.
+
+ fixed a storage leak in call() that appears to have been there since
+ 1983 or so -- a function without an explicit return that assigns a
+ string to a parameter leaked a Cell. thanks to moinak ghosh for
+ spotting this very subtle one.
+
+Jul 31, 2003:
+ fixed, thanks to andrey chernov and ruslan ermilov, a bug in lex.c
+ that mis-handled the character 255 in input. (it was being compared
+ to EOF with a signed comparison.)
+
+Jul 29, 2003:
+ fixed (i think) the long-standing botch that included the beginning of
+ line state ^ for RE's in the set of valid characters; this led to a
+ variety of odd problems, including failure to properly match certain
+ regular expressions in non-US locales. thanks to ruslan for keeping
+ at this one.
+
+Jul 28, 2003:
+ n-th try at getting internationalization right, with thanks to volker
+ kiefel, arnold robbins and ruslan ermilov for advice, though they
+ should not be blamed for the outcome. according to posix, "." is the
+ radix character in programs and command line arguments regardless of
+ the locale; otherwise, the locale should prevail for input and output
+ of numbers. so it's intended to work that way.
+
+ i have rescinded the attempt to use strcoll in expanding shorthands in
+ regular expressions (cclenter). its properties are much too
+ surprising; for example [a-c] matches aAbBc in locale en_US but abBcC
+ in locale fr_CA. i can see how this might arise by implementation
+ but i cannot explain it to a human user. (this behavior can be seen
+ in gawk as well; we're leaning on the same library.)
+
+ the issue appears to be that strcoll is meant for sorting, where
+ merging upper and lower case may make sense (though note that unix
+ sort does not do this by default either). it is not appropriate
+ for regular expressions, where the goal is to match specific
+ patterns of characters. in any case, the notations [:lower:], etc.,
+ are available in awk, and they are more likely to work correctly in
+ most locales.
+
+ a moratorium is hereby declared on internationalization changes.
+ i apologize to friends and colleagues in other parts of the world.
+ i would truly like to get this "right", but i don't know what
+ that is, and i do not want to keep making changes until it's clear.
+
+Jul 4, 2003:
+ fixed bug that permitted non-terminated RE, as in "awk /x".
+
+Jun 1, 2003:
+ subtle change to split: if source is empty, number of elems
+ is always 0 and the array is not set.
+
+Mar 21, 2003:
+ added some parens to isblank, in another attempt to make things
+ internationally portable.
+
+Mar 14, 2003:
+ the internationalization changes, somewhat modified, are now
+ reinstated. in theory awk will now do character comparisons
+ and case conversions in national language, but "." will always
+ be the decimal point separator on input and output regardless
+ of national language. isblank(){} has an #ifndef.
+
+ this no longer compiles on windows: LC_MESSAGES isn't defined
+ in vc6++.
+
+ fixed subtle behavior in field and record splitting: if FS is
+ a single character and RS is not empty, \n is NOT a separator.
+ this tortuous reading is found in the awk book; behavior now
+ matches gawk and mawk.
+
+Dec 13, 2002:
+ for the moment, the internationalization changes of nov 29 are
+ rolled back -- programs like x = 1.2 don't work in some locales,
+ because the parser is expecting x = 1,2. until i understand this
+ better, this will have to wait.
+
+Nov 29, 2002:
+ modified b.c (with tiny changes in main and run) to support
+ locales, using strcoll and iswhatever tests for posix character
+ classes. thanks to ruslan ermilov (ru@freebsd.org) for code.
+ the function isblank doesn't seem to have propagated to any
+ header file near me, so it's there explicitly. not properly
+ tested on non-ascii character sets by me.
+
+Jun 28, 2002:
+ modified run/format() and tran/getsval() to do a slightly better
+ job on using OFMT for output from print and CONVFMT for other
+ number->string conversions, as promised by posix and done by
+ gawk and mawk. there are still places where it doesn't work
+ right if CONVFMT is changed; by then the STR attribute of the
+ variable has been irrevocably set. thanks to arnold robbins for
+ code and examples.
+
+ fixed subtle bug in format that could get core dump. thanks to
+ Jaromir Dolecek <jdolecek@NetBSD.org> for finding and fixing.
+ minor cleanup in run.c / format() at the same time.
+
+ added some tests for null pointers to debugging printf's, which
+ were never intended for external consumption. thanks to dave
+ kerns (dkerns@lucent.com) for pointing this out.
+
+ GNU compatibility: an empty regexp matches anything (thanks to
+ dag-erling smorgrav, des@ofug.org). subject to reversion if
+ this does more harm than good.
+
+ pervasive small changes to make things more const-correct, as
+ reported by gcc's -Wwrite-strings. as it says in the gcc manual,
+ this may be more nuisance than useful. provoked by a suggestion
+ and code from arnaud desitter, arnaud@nimbus.geog.ox.ac.uk
+
+ minor documentation changes to note that this now compiles out
+ of the box on Mac OS X.
+
+Feb 10, 2002:
+ changed types in posix chars structure to quiet solaris cc.
+
+Jan 1, 2002:
+ fflush() or fflush("") flushes all files and pipes.
+
+ length(arrayname) returns number of elements; thanks to
+ arnold robbins for suggestion.
+
+ added a makefile.win to make it easier to build on windows.
+ based on dan allen's buildwin.bat.
+
+Nov 16, 2001:
+ added support for posix character class names like [:digit:],
+ which are not exactly shorter than [0-9] and perhaps no more
+ portable. thanks to dag-erling smorgrav for code.
+
+Feb 16, 2001:
+ removed -m option; no longer needed, and it was actually
+ broken (noted thanks to volker kiefel).
+
+Feb 10, 2001:
+ fixed an appalling bug in gettok: any sequence of digits, +,-, E, e,
+ and period was accepted as a valid number if it started with a period.
+ this would never have happened with the lex version.
+
+ other 1-character botches, now fixed, include a bare $ and a
+ bare " at the end of the input.
+
+Feb 7, 2001:
+ more (const char *) casts in b.c and tran.c to silence warnings.
+
+Nov 15, 2000:
+ fixed a bug introduced in august 1997 that caused expressions
+ like $f[1] to be syntax errors. thanks to arnold robbins for
+ noticing this and providing a fix.
+
+Oct 30, 2000:
+ fixed some nextfile bugs: not handling all cases. thanks to
+ arnold robbins for pointing this out. new regressions added.
+
+ close() is now a function. it returns whatever the library
+ fclose returns, and -1 for closing a file or pipe that wasn't
+ opened.
+
+Sep 24, 2000:
+ permit \n explicitly in character classes; won't work right
+ if comes in as "[\n]" but ok as /[\n]/, because of multiple
+ processing of \'s. thanks to arnold robbins.
+
+July 5, 2000:
+ minor fiddles in tran.c to keep compilers happy about uschar.
+ thanks to norman wilson.
+
+May 25, 2000:
+ yet another attempt at making 8-bit input work, with another
+ band-aid in b.c (member()), and some (uschar) casts to head
+ off potential errors in subscripts (like isdigit). also
+ changed HAT to NCHARS-2. thanks again to santiago vila.
+
+ changed maketab.c to ignore apparently out of range definitions
+ instead of halting; new freeBSD generates one. thanks to
+ jon snader <jsnader@ix.netcom.com> for pointing out the problem.
+
+May 2, 2000:
+ fixed an 8-bit problem in b.c by making several char*'s into
+ unsigned char*'s. not clear i have them all yet. thanks to
+ Santiago Vila <sanvila@unex.es> for the bug report.
+
+Apr 21, 2000:
+ finally found and fixed a memory leak in function call; it's
+ been there since functions were added ~1983. thanks to
+ jon bentley for the test case that found it.
+
+ added test in envinit to catch environment "variables" with
+ names beginning with '='; thanks to Berend Hasselman.
+
+Jul 28, 1999:
+ added test in defn() to catch function foo(foo), which
+ otherwise recurses until core dump. thanks to arnold
+ robbins for noticing this.
+
+Jun 20, 1999:
+ added *bp in gettok in lex.c; appears possible to exit function
+ without terminating the string. thanks to russ cox.
+
+Jun 2, 1999:
+ added function stdinit() to run to initialize files[] array,
+ in case stdin, etc., are not constants; some compilers care.
+
+May 10, 1999:
+ replaced the ERROR ... FATAL, etc., macros with functions
+ based on vprintf, to avoid problems caused by overrunning
+ fixed-size errbuf array. thanks to ralph corderoy for the
+ impetus, and for pointing out a string termination bug in
+ qstring as well.
+
+Apr 21, 1999:
+ fixed bug that caused occasional core dumps with commandline
+ variable with value ending in \. (thanks to nelson beebe for
+ the test case.)
+
+Apr 16, 1999:
+ with code kindly provided by Bruce Lilly, awk now parses
+ /=/ and similar constructs more sensibly in more places.
+ Bruce also provided some helpful test cases.
+
+Apr 5, 1999:
+ changed true/false to True/False in run.c to make it
+ easier to compile with C++. Added some casts on malloc
+ and realloc to be honest about casts; ditto. changed
+ ltype int to long in struct rrow to reduce some 64-bit
+ complaints; other changes scattered throughout for the
+ same purpose. thanks to Nelson Beebe for these portability
+ improvements.
+
+ removed some horrible pointer-int casting in b.c and elsewhere
+ by adding ptoi and itonp to localize the casts, which are
+ all benign. fixed one incipient bug that showed up on sgi
+ in 64-bit mode.
+
+ reset lineno for new source file; include filename in error
+ message. also fixed line number error in continuation lines.
+ (thanks to Nelson Beebe for both of these.)
+
+Mar 24, 1999:
+ Nelson Beebe notes that irix 5.3 yacc dies with a bogus
+ error; use a newer version or switch to bison, since sgi
+ is unlikely to fix it.
+
+Mar 5, 1999:
+ changed isnumber to is_number to avoid the problem caused by
+ versions of ctype.h that include the name isnumber.
+
+ distribution now includes a script for building on a Mac,
+ thanks to Dan Allen.
+
+Feb 20, 1999:
+ fixed memory leaks in run.c (call) and tran.c (setfval).
+ thanks to Stephen Nutt for finding these and providing the fixes.
+
+Jan 13, 1999:
+ replaced srand argument by (unsigned int) in run.c;
+ avoids problem on Mac and potentially on Unix & Windows.
+ thanks to Dan Allen.
+
+ added a few (int) casts to silence useless compiler warnings.
+ e.g., errorflag= in run.c jump().
+
+ added proctab.c to the bundle outout; one less thing
+ to have to compile out of the box.
+
+ added calls to _popen and _pclose to the win95 stub for
+ pipes (thanks to Steve Adams for this helpful suggestion).
+ seems to work, though properties are not well understood
+ by me, and it appears that under some circumstances the
+ pipe output is truncated. Be careful.
+
+Oct 19, 1998:
+ fixed a couple of bugs in getrec: could fail to update $0
+ after a getline var; because inputFS wasn't initialized,
+ could split $0 on every character, a misleading diversion.
+
+ fixed caching bug in makedfa: LRU was actually removing
+ least often used.
+
+ thanks to ross ridge for finding these, and for providing
+ great bug reports.
+
+May 12, 1998:
+ fixed potential bug in readrec: might fail to update record
+ pointer after growing. thanks to dan levy for spotting this
+ and suggesting the fix.
+
+Mar 12, 1998:
+ added -V to print version number and die.
+
+Feb 11, 1998:
+ subtle silent bug in lex.c: if the program ended with a number
+ longer than 1 digit, part of the input would be pushed back and
+ parsed again because token buffer wasn't terminated right.
+ example: awk 'length($0) > 10'. blush. at least i found it
+ myself.
+
+Aug 31, 1997:
+ s/adelete/awkdelete/: SGI uses this in malloc.h.
+ thanks to nelson beebe for pointing this one out.
+
+Aug 21, 1997:
+ fixed some bugs in sub and gsub when replacement includes \\.
+ this is a dark, horrible corner, but at least now i believe that
+ the behavior is the same as gawk and the intended posix standard.
+ thanks to arnold robbins for advice here.
+
+Aug 9, 1997:
+ somewhat regretfully, replaced the ancient lex-based lexical
+ analyzer with one written in C. it's longer, generates less code,
+ and more portable; the old one depended too much on mysterious
+ properties of lex that were not preserved in other environments.
+ in theory these recognize the same language.
+
+ now using strtod to test whether a string is a number, instead of
+ the convoluted original function. should be more portable and
+ reliable if strtod is implemented right.
+
+ removed now-pointless optimization in makefile that tries to avoid
+ recompilation when awkgram.y is changed but symbols are not.
+
+ removed most fixed-size arrays, though a handful remain, some
+ of which are unchecked. you have been warned.
+
+Aug 4, 1997:
+ with some trepidation, replaced the ancient code that managed
+ fields and $0 in fixed-size arrays with arrays that grow on
+ demand. there is still some tension between trying to make this
+ run fast and making it clean; not sure it's right yet.
+
+ the ill-conceived -mr and -mf arguments are now useful only
+ for debugging. previous dynamic string code removed.
+
+ numerous other minor cleanups along the way.
+
+Jul 30, 1997:
+ using code provided by dan levy (to whom profuse thanks), replaced
+ fixed-size arrays and awkward kludges by a fairly uniform mechanism
+ to grow arrays as needed for printf, sub, gsub, etc.
+
+Jul 23, 1997:
+ falling off the end of a function returns "" and 0, not 0.
+ thanks to arnold robbins.
+
+Jun 17, 1997:
+ replaced several fixed-size arrays by dynamically-created ones
+ in run.c; added overflow tests to some previously unchecked cases.
+ getline, toupper, tolower.
+
+ getline code is still broken in that recursive calls may wind
+ up using the same space. [fixed later]
+
+ increased RECSIZE to 8192 to push problems further over the horizon.
+
+ added \r to \n as input line separator for programs, not data.
+ damn CRLFs.
+
+ modified format() to permit explicit printf("%c", 0) to include
+ a null byte in output. thanks to ken stailey for the fix.
+
+ added a "-safe" argument that disables file output (print >,
+ print >>), process creation (cmd|getline, print |, system), and
+ access to the environment (ENVIRON). this is a first approximation
+ to a "safe" version of awk, but don't rely on it too much. thanks
+ to joan feigenbaum and matt blaze for the inspiration long ago.
+
+Jul 8, 1996:
+ fixed long-standing bug in sub, gsub(/a/, "\\\\&"); thanks to
+ ralph corderoy.
+
+Jun 29, 1996:
+ fixed awful bug in new field splitting; didn't get all the places
+ where input was done.
+
+Jun 28, 1996:
+ changed field-splitting to conform to posix definition: fields are
+ split using the value of FS at the time of input; it used to be
+ the value when the field or NF was first referred to, a much less
+ predictable definition. thanks to arnold robbins for encouragement
+ to do the right thing.
+
+May 28, 1996:
+ fixed appalling but apparently unimportant bug in parsing octal
+ numbers in reg exprs.
+
+ explicit hex in reg exprs now limited to 2 chars: \xa, \xaa.
+
+May 27, 1996:
+ cleaned up some declarations so gcc -Wall is now almost silent.
+
+ makefile now includes backup copies of ytab.c and lexyy.c in case
+ one makes before looking; it also avoids recreating lexyy.c unless
+ really needed.
+
+ s/aprintf/awkprint, s/asprintf/awksprintf/ to avoid some name clashes
+ with unwisely-written header files.
+
+ thanks to jeffrey friedl for several of these.
+
+May 26, 1996:
+ an attempt to rationalize the (unsigned) char issue. almost all
+ instances of unsigned char have been removed; the handful of places
+ in b.c where chars are used as table indices have been hand-crafted.
+ added some latin-1 tests to the regression, but i'm not confident;
+ none of my compilers seem to care much. thanks to nelson beebe for
+ pointing out some others that do care.
+
+May 2, 1996:
+ removed all register declarations.
+
+ enhanced split(), as in gawk, etc: split(s, a, "") splits s into
+ a[1]...a[length(s)] with each character a single element.
+
+ made the same changes for field-splitting if FS is "".
+
+ added nextfile, as in gawk: causes immediate advance to next
+ input file. (thanks to arnold robbins for inspiration and code).
+
+ small fixes to regexpr code: can now handle []], [[], and
+ variants; [] is now a syntax error, rather than matching
+ everything; [z-a] is now empty, not z. far from complete
+ or correct, however. (thanks to jeffrey friedl for pointing out
+ some awful behaviors.)
+
+Apr 29, 1996:
+ replaced uchar by uschar everywhere; apparently some compilers
+ usurp this name and this causes conflicts.
+
+ fixed call to time in run.c (bltin); arg is time_t *.
+
+ replaced horrible pointer/long punning in b.c by a legitimate
+ union. should be safer on 64-bit machines and cleaner everywhere.
+ (thanks to nelson beebe for pointing out some of these problems.)
+
+ replaced nested comments by #if 0...#endif in run.c, lib.c.
+
+ removed getsval, setsval, execute macros from run.c and lib.c.
+ machines are 100x faster than they were when these macros were
+ first used.
+
+ revised filenames: awk.g.y => awkgram.y, awk.lx.l => awklex.l,
+ y.tab.[ch] => ytab.[ch], lex.yy.c => lexyy.c, all in the aid of
+ portability to nameless systems.
+
+ "make bundle" now includes yacc and lex output files for recipients
+ who don't have yacc or lex.
+
+Aug 15, 1995:
+ initialized Cells in setsymtab more carefully; some fields
+ were not set. (thanks to purify, all of whose complaints i
+ think i now understand.)
+
+ fixed at least one error in gsub that looked at -1-th element
+ of an array when substituting for a null match (e.g., $).
+
+ delete arrayname is now legal; it clears the elements but leaves
+ the array, which may not be the right behavior.
+
+ modified makefile: my current make can't cope with the test used
+ to avoid unnecessary yacc invocations.
+
+Jul 17, 1995:
+ added dynamically growing strings to awk.lx.l and b.c
+ to permit regular expressions to be much bigger.
+ the state arrays can still overflow.
+
+Aug 24, 1994:
+ detect duplicate arguments in function definitions (mdm).
+
+May 11, 1994:
+ trivial fix to printf to limit string size in sub().
+
+Apr 22, 1994:
+ fixed yet another subtle self-assignment problem:
+ $1 = $2; $1 = $1 clobbered $1.
+
+ Regression tests now use private echo, to avoid quoting problems.
+
+Feb 2, 1994:
+ changed error() to print line number as %d, not %g.
+
+Jul 23, 1993:
+ cosmetic changes: increased sizes of some arrays,
+ reworded some error messages.
+
+ added CONVFMT as in posix (just replaced OFMT in getsval)
+
+ FILENAME is now "" until the first thing that causes a file
+ to be opened.
+
+Nov 28, 1992:
+ deleted yyunput and yyoutput from proto.h;
+ different versions of lex give these different declarations.
+
+May 31, 1992:
+ added -mr N and -mf N options: more record and fields.
+ these really ought to adjust automatically.
+
+ cleaned up some error messages; "out of space" now means
+ malloc returned NULL in all cases.
+
+ changed rehash so that if it runs out, it just returns;
+ things will continue to run slow, but maybe a bit longer.
+
+Apr 24, 1992:
+ remove redundant close of stdin when using -f -.
+
+ got rid of core dump with -d; awk -d just prints date.
+
+Apr 12, 1992:
+ added explicit check for /dev/std(in,out,err) in redirection.
+ unlike gawk, no /dev/fd/n yet.
+
+ added (file/pipe) builtin. hard to test satisfactorily.
+ not posix.
+
+Feb 20, 1992:
+ recompile after abortive changes; should be unchanged.
+
+Dec 2, 1991:
+ die-casting time: converted to ansi C, installed that.
+
+Nov 30, 1991:
+ fixed storage leak in freefa, failing to recover [N]CCL.
+ thanks to Bill Jones (jones@cs.usask.ca)
+
+Nov 19, 1991:
+ use RAND_MAX instead of literal in builtin().
+
+Nov 12, 1991:
+ cranked up some fixed-size arrays in b.c, and added a test for
+ overflow in penter. thanks to mark larsen.
+
+Sep 24, 1991:
+ increased buffer in gsub. a very crude fix to a general problem.
+ and again on Sep 26.
+
+Aug 18, 1991:
+ enforce variable name syntax for commandline variables: has to
+ start with letter or _.
+
+Jul 27, 1991:
+ allow newline after ; in for statements.
+
+Jul 21, 1991:
+ fixed so that in self-assignment like $1=$1, side effects
+ like recomputing $0 take place. (this is getting subtle.)
+
+Jun 30, 1991:
+ better test for detecting too-long output record.
+
+Jun 2, 1991:
+ better defense against very long printf strings.
+ made break and continue illegal outside of loops.
+
+May 13, 1991:
+ removed extra arg on gettemp, tempfree. minor error message rewording.
+
+May 6, 1991:
+ fixed silly bug in hex parsing in hexstr().
+ removed an apparently unnecessary test in isnumber().
+ warn about weird printf conversions.
+ fixed unchecked array overwrite in relex().
+
+ changed for (i in array) to access elements in sorted order.
+ then unchanged it -- it really does run slower in too many cases.
+ left the code in place, commented out.
+
+Feb 10, 1991:
+ check error status on all writes, to avoid banging on full disks.
+
+Jan 28, 1991:
+ awk -f - reads the program from stdin.
+
+Jan 11, 1991:
+ failed to set numeric state on $0 in cmd|getline context in run.c.
+
+Nov 2, 1990:
+ fixed sleazy test for integrality in getsval; use modf.
+
+Oct 29, 1990:
+ fixed sleazy buggy code in lib.c that looked (incorrectly) for
+ too long input lines.
+
+Oct 14, 1990:
+ fixed the bug on p. 198 in which it couldn't deduce that an
+ argument was an array in some contexts. replaced the error
+ message in intest() by code that damn well makes it an array.
+
+Oct 8, 1990:
+ fixed horrible bug: types and values were not preserved in
+ some kinds of self-assignment. (in assign().)
+
+Aug 24, 1990:
+ changed NCHARS to 256 to handle 8-bit characters in strings
+ presented to match(), etc.
+
+Jun 26, 1990:
+ changed struct rrow (awk.h) to use long instead of int for lval,
+ since cfoll() stores a pointer in it. now works better when int's
+ are smaller than pointers!
+
+May 6, 1990:
+ AVA fixed the grammar so that ! is uniformly of the same precedence as
+ unary + and -. This renders illegal some constructs like !x=y, which
+ now has to be parenthesized as !(x=y), and makes others work properly:
+ !x+y is (!x)+y, and x!y is x !y, not two pattern-action statements.
+ (These problems were pointed out by Bob Lenk of Posix.)
+
+ Added \x to regular expressions (already in strings).
+ Limited octal to octal digits; \8 and \9 are not octal.
+ Centralized the code for parsing escapes in regular expressions.
+ Added a bunch of tests to T.re and T.sub to verify some of this.
+
+Feb 9, 1990:
+ fixed null pointer dereference bug in main.c: -F[nothing]. sigh.
+
+ restored srand behavior: it returns the current seed.
+
+Jan 18, 1990:
+ srand now returns previous seed value (0 to start).
+
+Jan 5, 1990:
+ fix potential problem in tran.c -- something was freed,
+ then used in freesymtab.
+
+Oct 18, 1989:
+ another try to get the max number of open files set with
+ relatively machine-independent code.
+
+ small fix to input() in case of multiple reads after EOF.
+
+Oct 11, 1989:
+ FILENAME is now defined in the BEGIN block -- too many old
+ programs broke.
+
+ "-" means stdin in getline as well as on the commandline.
+
+ added a bunch of casts to the code to tell the truth about
+ char * vs. unsigned char *, a right royal pain. added a
+ setlocale call to the front of main, though probably no one
+ has it usefully implemented yet.
+
+Aug 24, 1989:
+ removed redundant relational tests against nullnode if parse
+ tree already had a relational at that point.
+
+Aug 11, 1989:
+ fixed bug: commandline variable assignment has to look like
+ var=something. (consider the man page for =, in file =.1)
+
+ changed number of arguments to functions to static arrays
+ to avoid repeated malloc calls.
+
+Aug 2, 1989:
+ restored -F (space) separator
+
+Jul 30, 1989:
+ added -v x=1 y=2 ... for immediate commandline variable assignment;
+ done before the BEGIN block for sure. they have to precede the
+ program if the program is on the commandline.
+ Modified Aug 2 to require a separate -v for each assignment.
+
+Jul 10, 1989:
+ fixed ref-thru-zero bug in environment code in tran.c
+
+Jun 23, 1989:
+ add newline to usage message.
+
+Jun 14, 1989:
+ added some missing ansi printf conversion letters: %i %X %E %G.
+ no sensible meaning for h or L, so they may not do what one expects.
+
+ made %* conversions work.
+
+ changed x^y so that if n is a positive integer, it's done
+ by explicit multiplication, thus achieving maximum accuracy.
+ (this should be done by pow() but it seems not to be locally.)
+ done to x ^= y as well.
+
+Jun 4, 1989:
+ ENVIRON array contains environment: if shell variable V=thing,
+ ENVIRON["V"] is "thing"
+
+ multiple -f arguments permitted. error reporting is naive.
+ (they were permitted before, but only the last was used.)
+
+ fixed a really stupid botch in the debugging macro dprintf
+
+ fixed order of evaluation of commandline assignments to match
+ what the book claims: an argument of the form x=e is evaluated
+ at the time it would have been opened if it were a filename (p 63).
+ this invalidates the suggested answer to ex 4-1 (p 195).
+
+ removed some code that permitted -F (space) fieldseparator,
+ since it didn't quite work right anyway. (restored aug 2)
+
+Apr 27, 1989:
+ Line number now accumulated correctly for comment lines.
+
+Apr 26, 1989:
+ Debugging output now includes a version date,
+ if one compiles it into the source each time.
+
+Apr 9, 1989:
+ Changed grammar to prohibit constants as 3rd arg of sub and gsub;
+ prevents class of overwriting-a-constant errors. (Last one?)
+ This invalidates the "banana" example on page 43 of the book.
+
+ Added \a ("alert"), \v (vertical tab), \xhhh (hexadecimal),
+ as in ANSI, for strings. Rescinded the sloppiness that permitted
+ non-octal digits in \ooo. Warning: not all compilers and libraries
+ will be able to deal with \x correctly.
+
+Jan 9, 1989:
+ Fixed bug that caused tempcell list to contain a duplicate.
+ The fix is kludgy.
+
+Dec 17, 1988:
+ Catches some more commandline errors in main.
+ Removed redundant decl of modf in run.c (confuses some compilers).
+ Warning: there's no single declaration of malloc, etc., in awk.h
+ that seems to satisfy all compilers.
+
+Dec 7, 1988:
+ Added a bit of code to error printing to avoid printing nulls.
+ (Not clear that it actually would.)
+
+Nov 27, 1988:
+ With fear and trembling, modified the grammar to permit
+ multiple pattern-action statements on one line without
+ an explicit separator. By definition, this capitulation
+ to the ghost of ancient implementations remains undefined
+ and thus subject to change without notice or apology.
+ DO NOT COUNT ON IT.
+
+Oct 30, 1988:
+ Fixed bug in call() that failed to recover storage.
+
+ A warning is now generated if there are more arguments
+ in the call than in the definition (in lieu of fixing
+ another storage leak).
+
+Oct 20, 1988:
+ Fixed %c: if expr is numeric, use numeric value;
+ otherwise print 1st char of string value. still
+ doesn't work if the value is 0 -- won't print \0.
+
+ Added a few more checks for running out of malloc.
+
+Oct 12, 1988:
+ Fixed bug in call() that freed local arrays twice.
+
+ Fixed to handle deletion of non-existent array right;
+ complains about attempt to delete non-array element.
+
+Sep 30, 1988:
+ Now guarantees to evaluate all arguments of built-in
+ functions, as in C; the appearance is that arguments
+ are evaluated before the function is called. Places
+ affected are sub (gsub was ok), substr, printf, and
+ all the built-in arithmetic functions in bltin().
+ A warning is generated if a bltin() is called with
+ the wrong number of arguments.
+
+ This requires changing makeprof on p167 of the book.
+
+Aug 23, 1988:
+ setting FILENAME in BEGIN caused core dump, apparently
+ because it was freeing space not allocated by malloc.
+
+July 24, 1988:
+ fixed egregious error in toupper/tolower functions.
+ still subject to rescinding, however.
+
+July 2, 1988:
+ flush stdout before opening file or pipe
+
+July 2, 1988:
+ performance bug in b.c/cgoto(): not freeing some sets of states.
+ partial fix only right now, and the number of states increased
+ to make it less obvious.
+
+June 1, 1988:
+ check error status on close
+
+May 28, 1988:
+ srand returns seed value it's using.
+ see 1/18/90
+
+May 22, 1988:
+ Removed limit on depth of function calls.
+
+May 10, 1988:
+ Fixed lib.c to permit _ in commandline variable names.
+
+Mar 25, 1988:
+ main.c fixed to recognize -- as terminator of command-
+ line options. Illegal options flagged.
+ Error reporting slightly cleaned up.
+
+Dec 2, 1987:
+ Newer C compilers apply a strict scope rule to extern
+ declarations within functions. Two extern declarations in
+ lib.c and tran.c have been moved to obviate this problem.
+
+Oct xx, 1987:
+ Reluctantly added toupper and tolower functions.
+ Subject to rescinding without notice.
+
+Sep 17, 1987:
+ Error-message printer had printf(s) instead of
+ printf("%s",s); got core dumps when the message
+ included a %.
+
+Sep 12, 1987:
+ Very long printf strings caused core dump;
+ fixed aprintf, asprintf, format to catch them.
+ Can still get a core dump in printf itself.

+****************************************************************/
+
+This is the version of awk described in "The AWK Programming Language",
+by Al Aho, Brian Kernighan, and Peter Weinberger
+(Addison-Wesley, 1988, ISBN 0-201-07981-X).
+
+Changes, mostly bug fixes and occasional enhancements, are listed
+in FIXES. If you distribute this code further, please please please
+distribute FIXES with it. If you find errors, please report them
+to bwk@bell-labs.com. Thanks.
+
+The program itself is created by
+ make
+which should produce a sequence of messages roughly like this:
+
+ yacc -d awkgram.y
+
+conflicts: 43 shift/reduce, 85 reduce/reduce
+ mv y.tab.c ytab.c
+ mv y.tab.h ytab.h
+ cc -c ytab.c
+ cc -c b.c
+ cc -c main.c
+ cc -c parse.c
+ cc maketab.c -o maketab
+ ./maketab >proctab.c
+ cc -c proctab.c
+ cc -c tran.c
+ cc -c lib.c
+ cc -c run.c
+ cc -c lex.c
+ cc ytab.o b.o main.o parse.o proctab.o tran.o lib.o run.o lex.o -lm
+
+This produces an executable a.out; you will eventually want to
+move this to some place like /usr/bin/awk.
+
+If your system does not have yacc or bison (the GNU
+equivalent), you must compile the pieces manually. We have
+included yacc output in ytab.c and ytab.h, and backup copies in
+case you overwrite them. We have also included a copy of
+proctab.c so you do not need to run maketab.
+
+NOTE: This version uses ANSI C, as you should also. We have
+compiled this without any changes using gcc -Wall and/or local C
+compilers on a variety of systems, but new systems or compilers
+may raise some new complaint; reports of difficulties are
+welcome.
+
+This also compiles with Visual C++ on all flavors of Windows,
+*if* you provide versions of popen and pclose. The file
+missing95.c contains versions that can be used to get started
+with, though the underlying support has mysterious properties,
+the symptom of which can be truncated pipe output. Beware. The
+file makefile.win gives hints on how to proceed; if you run
+vcvars32.bat, it will set up necessary paths and parameters so
+you can subsequently run nmake -f makefile.win. Beware also that
+when running on Windows under command.com, various quoting
+conventions are different from Unix systems: single quotes won't
+work around arguments, and various characters like % are
+interpreted within double quotes.
+
+This compiles without change on Macintosh OS X using gcc and
+the standard developer tools.
+
+This is also said to compile on Macintosh OS 9 systems, using the
+file "buildmac" provided by Dan Allen (danallen@microsoft.com),
+to whom many thanks.
+
+The version of malloc that comes with some systems is sometimes
+astonishly slow. If awk seems slow, you might try fixing that.
+More generally, turning on optimization can significantly improve
+awk's speed, perhaps by 1/3 for highest levels.

+.SH NAME
+awk \- pattern-directed scanning and processing language
+.SH SYNOPSIS
+.B awk
+[
+.BI \-F
+.I fs
+]
+[
+.BI \-v
+.I var=value
+]
+[
+.I 'prog'
+|
+.BI \-f
+.I progfile
+]
+[
+.I file ...
+]
+.SH DESCRIPTION
+.I Awk
+scans each input
+.I file
+for lines that match any of a set of patterns specified literally in
+.IR prog
+or in one or more files
+specified as
+.B \-f
+.IR progfile .
+With each pattern
+there can be an associated action that will be performed
+when a line of a
+.I file
+matches the pattern.
+Each line is matched against the
+pattern portion of every pattern-action statement;
+the associated action is performed for each matched pattern.
+The file name
+.B \-
+means the standard input.
+Any
+.IR file
+of the form
+.I var=value
+is treated as an assignment, not a filename,
+and is executed at the time it would have been opened if it were a filename.
+The option
+.B \-v
+followed by
+.I var=value
+is an assignment to be done before
+.I prog
+is executed;
+any number of
+.B \-v
+options may be present.
+The
+.B \-F
+.IR fs
+option defines the input field separator to be the regular expression
+.IR fs.
+.PP
+An input line is normally made up of fields separated by white space,
+or by regular expression
+.BR FS .
+The fields are denoted
+.BR $1 ,
+.BR $2 ,
+\&..., while
+.B $0
+refers to the entire line.
+If
+.BR FS
+is null, the input line is split into one field per character.
+.PP
+A pattern-action statement has the form
+.IP
+.IB pattern " { " action " }
+.PP
+A missing
+.BI { " action " }
+means print the line;
+a missing pattern always matches.
+Pattern-action statements are separated by newlines or semicolons.
+.PP
+An action is a sequence of statements.
+A statement can be one of the following:
+.PP
+.EX
+.ta \w'\f(CWdelete array[expression]'u
+.RS
+.nf
+.ft CW
+if(\fI expression \fP)\fI statement \fP\fR[ \fPelse\fI statement \fP\fR]\fP

+.PP
+Statements are terminated by
+semicolons, newlines or right braces.
+An empty
+.I expression-list
+stands for
+.BR $0 .
+String constants are quoted \&\f(CW"\ "\fR,
+with the usual C escapes recognized within.
+Expressions take on string or numeric values as appropriate,
+and are built using the operators
+.B + \- * / % ^
+(exponentiation), and concatenation (indicated by white space).
+The operators
+.B
+! ++ \-\- += \-= *= /= %= ^= > >= < <= == != ?:
+are also available in expressions.
+Variables may be scalars, array elements
+(denoted
+.IB x [ i ] )
+or fields.
+Variables are initialized to the null string.
+Array subscripts may be any string,
+not necessarily numeric;
+this allows for a form of associative memory.
+Multiple subscripts such as
+.B [i,j,k]
+are permitted; the constituents are concatenated,
+separated by the value of
+.BR SUBSEP .
+.PP
+The
+.B print
+statement prints its arguments on the standard output
+(or on a file if
+.BI > file
+or
+.BI >> file
+is present or on a pipe if
+.BI | cmd
+is present), separated by the current output field separator,
+and terminated by the output record separator.
+.I file
+and
+.I cmd
+may be literal names or parenthesized expressions;
+identical string values in different statements denote
+the same open file.
+The
+.B printf
+statement formats its expression list according to the format
+(see
+.IR printf (3)) .
+The built-in function
+.BI close( expr )
+closes the file or pipe
+.IR expr .
+The built-in function
+.BI fflush( expr )
+flushes any buffered output for the file or pipe
+.IR expr .
+.PP
+The mathematical functions
+.BR exp ,
+.BR log ,
+.BR sqrt ,
+.BR sin ,
+.BR cos ,
+and
+.BR atan2
+are built in.
+Other built-in functions:
+.TF length
+.TP
+.B length
+the length of its argument
+taken as a string,
+or of
+.B $0
+if no argument.
+.TP
+.B rand
+random number on (0,1)
+.TP
+.B srand
+sets seed for
+.B rand
+and returns the previous seed.
+.TP
+.B int
+truncates to an integer value
+.TP
+.BI substr( s , " m" , " n\fB)
+the
+.IR n -character
+substring of
+.I s
+that begins at position
+.IR m
+counted from 1.
+.TP
+.BI index( s , " t" )
+the position in
+.I s
+where the string
+.I t
+occurs, or 0 if it does not.
+.TP
+.BI match( s , " r" )
+the position in
+.I s
+where the regular expression
+.I r
+occurs, or 0 if it does not.
+The variables
+.B RSTART
+and
+.B RLENGTH
+are set to the position and length of the matched string.
+.TP
+.BI split( s , " a" , " fs\fB)
+splits the string
+.I s
+into array elements
+.IB a [1] ,
+.IB a [2] ,
+\&...,
+.IB a [ n ] ,
+and returns
+.IR n .
+The separation is done with the regular expression
+.I fs
+or with the field separator
+.B FS
+if
+.I fs
+is not given.
+An empty string as field separator splits the string
+into one array element per character.
+.TP
+.BI sub( r , " t" , " s\fB)
+substitutes
+.I t
+for the first occurrence of the regular expression
+.I r
+in the string
+.IR s .
+If
+.I s
+is not given,
+.B $0
+is used.
+.TP
+.B gsub
+same as
+.B sub
+except that all occurrences of the regular expression
+are replaced;
+.B sub
+and
+.B gsub
+return the number of replacements.
+.TP
+.BI sprintf( fmt , " expr" , " ...\fB )
+the string resulting from formatting
+.I expr ...
+according to the
+.IR printf (3)
+format
+.I fmt
+.TP
+.BI system( cmd )
+executes
+.I cmd
+and returns its exit status
+.TP
+.BI tolower( str )
+returns a copy of
+.I str
+with all upper-case characters translated to their
+corresponding lower-case equivalents.
+.TP
+.BI toupper( str )
+returns a copy of
+.I str
+with all lower-case characters translated to their
+corresponding upper-case equivalents.
+.PD
+.PP
+The ``function''
+.B getline
+sets
+.B $0
+to the next input record from the current input file;
+.B getline
+.BI < file
+sets
+.B $0
+to the next record from
+.IR file .
+.B getline
+.I x
+sets variable
+.I x
+instead.
+Finally,
+.IB cmd " | getline
+pipes the output of
+.I cmd
+into
+.BR getline ;
+each call of
+.B getline
+returns the next line of output from
+.IR cmd .
+In all cases,
+.B getline
+returns 1 for a successful input,
+0 for end of file, and \-1 for an error.
+.PP
+Patterns are arbitrary Boolean combinations
+(with
+.BR "! || &&" )
+of regular expressions and
+relational expressions.
+Regular expressions are as in
+.IR egrep ;
+see
+.IR grep (1).
+Isolated regular expressions
+in a pattern apply to the entire line.
+Regular expressions may also occur in
+relational expressions, using the operators
+.BR ~
+and
+.BR !~ .
+.BI / re /
+is a constant regular expression;
+any string (constant or variable) may be used
+as a regular expression, except in the position of an isolated regular expression
+in a pattern.
+.PP
+A pattern may consist of two patterns separated by a comma;
+in this case, the action is performed for all lines
+from an occurrence of the first pattern
+though an occurrence of the second.
+.PP
+A relational expression is one of the following:
+.IP
+.I expression matchop regular-expression
+.br
+.I expression relop expression
+.br
+.IB expression " in " array-name
+.br
+.BI ( expr , expr,... ") in " array-name
+.PP
+where a relop is any of the six relational operators in C,
+and a matchop is either
+.B ~
+(matches)
+or
+.B !~
+(does not match).
+A conditional is an arithmetic expression,
+a relational expression,
+or a Boolean combination
+of these.
+.PP
+The special patterns
+.B BEGIN
+and
+.B END
+may be used to capture control before the first input line is read
+and after the last.
+.B BEGIN
+and
+.B END
+do not combine with other patterns.
+.PP
+Variable names with special meanings:
+.TF FILENAME
+.TP
+.B CONVFMT
+conversion format used when converting numbers
+(default
+.BR "%.6g" )
+.TP
+.B FS
+regular expression used to separate fields; also settable
+by option
+.BI \-F fs.
+.TP
+.BR NF
+number of fields in the current record
+.TP
+.B NR
+ordinal number of the current record
+.TP
+.B FNR
+ordinal number of the current record in the current file
+.TP
+.B FILENAME
+the name of the current input file
+.TP
+.B RS
+input record separator (default newline)
+.TP
+.B OFS
+output field separator (default blank)
+.TP
+.B ORS
+output record separator (default newline)
+.TP
+.B OFMT
+output format for numbers (default
+.BR "%.6g" )
+.TP
+.B SUBSEP
+separates multiple subscripts (default 034)
+.TP
+.B ARGC
+argument count, assignable
+.TP
+.B ARGV
+argument array, assignable;
+non-null members are taken as filenames
+.TP
+.B ENVIRON
+array of environment variables; subscripts are names.
+.PD
+.PP
+Functions may be defined (at the position of a pattern-action statement) thus:
+.IP
+.B
+function foo(a, b, c) { ...; return x }
+.PP
+Parameters are passed by value if scalar and by reference if array name;
+functions may be called recursively.
+Parameters are local to the function; all other variables are global.
+Thus local variables may be created by providing excess parameters in
+the function definition.
+.SH EXAMPLES
+.TP
+.EX
+length($0) > 72
+.EE
+Print lines longer than 72 characters.
+.TP
+.EX
+{ print $2, $1 }
+.EE
+Print first two fields in opposite order.
+.PP
+.EX
+BEGIN { FS = ",[ \et]*|[ \et]+" }
+ { print $2, $1 }
+.EE
+.ns
+.IP
+Same, with input fields separated by comma and/or blanks and tabs.
+.PP
+.EX
+.nf
+ { s += $1 }
+END { print "sum is", s, " average is", s/NR }
+.fi
+.EE
+.ns
+.IP
+Add up first column, print sum and average.
+.TP
+.EX
+/start/, /stop/
+.EE
+Print all lines between start/stop pairs.
+.PP
+.EX
+.nf
+BEGIN { # Simulate echo(1)
+ for (i = 1; i < ARGC; i++) printf "%s ", ARGV[i]
+ printf "\en"

+.B nawk

+.BI \-F
+.I fs
+]
+[
+.BI \-v
+.I var=value
+]
+[
+.I 'prog'
+|

+[
+.I file ...
+]
+.SH DESCRIPTION
+.I Nawk
+scans each input
+.I file
+for lines that match any of a set of patterns specified literally in
+.IR prog
+or in one or more files
+specified as
+.B \-f
+.IR progfile .
+With each pattern
+there can be an associated action that will be performed
+when a line of a
+.I file
+matches the pattern.
+Each line is matched against the
+pattern portion of every pattern-action statement;
+the associated action is performed for each matched pattern.
+The file name
+.B \-
+means the standard input.
+Any
+.IR file
+of the form
+.I var=value
+is treated as an assignment, not a filename,
+and is executed at the time it would have been opened if it were a filename.
+The option
+.B \-v
+followed by
+.I var=value
+is an assignment to be done before
+.I prog
+is executed;
+any number of
+.B \-v
+options may be present.
+The
+.B \-F
+.IR fs
+option defines the input field separator to be the regular expression
+.IR fs.
+.PP
+An input line is normally made up of fields separated by white space,
+or by regular expression
+.BR FS .
+The fields are denoted
+.BR $1 ,
+.BR $2 ,
+\&..., while
+.B $0
+refers to the entire line.
+If
+.BR FS
+is null, the input line is split into one field per character.
+.PP
+A pattern-action statement has the form
+.IP
+.IB pattern " { " action " }
+.PP
+A missing
+.BI { " action " }
+means print the line;
+a missing pattern always matches.
+Pattern-action statements are separated by newlines or semicolons.
+.PP
+An action is a sequence of statements.
+A statement can be one of the following:
+.PP
+.EX
+.ta \w'\f(CWdelete array[expression]'u
+.RS
+.nf
+.ft CW

+.fi
+.RE
+.EE
+.DT
+.PP
+Statements are terminated by
+semicolons, newlines or right braces.
+An empty
+.I expression-list
+stands for
+.BR $0 .
+String constants are quoted \&\f(CW"\ "\fR,
+with the usual C escapes recognized within.
+Expressions take on string or numeric values as appropriate,
+and are built using the operators
+.B + \- * / % ^
+(exponentiation), and concatenation (indicated by white space).
+The operators
+.B
+! ++ \-\- += \-= *= /= %= ^= > >= < <= == != ?:
+are also available in expressions.
+Variables may be scalars, array elements
+(denoted
+.IB x [ i ] )
+or fields.
+Variables are initialized to the null string.
+Array subscripts may be any string,
+not necessarily numeric;
+this allows for a form of associative memory.
+Multiple subscripts such as
+.B [i,j,k]
+are permitted; the constituents are concatenated,
+separated by the value of
+.BR SUBSEP .
+.PP
+The
+.B print
+statement prints its arguments on the standard output
+(or on a file if
+.BI > file
+or
+.BI >> file
+is present or on a pipe if
+.BI | cmd
+is present), separated by the current output field separator,
+and terminated by the output record separator.
+.I file
+and
+.I cmd
+may be literal names or parenthesized expressions;
+identical string values in different statements denote
+the same open file.
+The
+.B printf
+statement formats its expression list according to the format
+(see
+.IR printf (3)) .
+The built-in function
+.BI close( expr )
+closes the file or pipe
+.IR expr .
+The built-in function
+.BI fflush( expr )
+flushes any buffered output for the file or pipe
+.IR expr .
+.PP
+The mathematical functions
+.BR exp ,
+.BR log ,
+.BR sqrt ,
+.BR sin ,
+.BR cos ,
+and
+.BR atan2
+are built in.
+Other built-in functions:
+.TF length
+.TP
+.B length
+the length of its argument
+taken as a string,
+or of
+.B $0
+if no argument.
+.TP
+.B rand
+random number on (0,1)
+.TP
+.B srand
+sets seed for
+.B rand
+and returns the previous seed.
+.TP
+.B int
+truncates to an integer value
+.TP
+.BI substr( s , " m" , " n\fB)
+the
+.IR n -character
+substring of
+.I s
+that begins at position
+.IR m
+counted from 1.
+.TP
+.BI index( s , " t" )
+the position in
+.I s
+where the string
+.I t
+occurs, or 0 if it does not.
+.TP
+.BI match( s , " r" )
+the position in
+.I s
+where the regular expression
+.I r
+occurs, or 0 if it does not.
+The variables
+.B RSTART
+and
+.B RLENGTH
+are set to the position and length of the matched string.
+.TP
+.BI split( s , " a" , " fs\fB)
+splits the string
+.I s
+into array elements
+.IB a [1] ,
+.IB a [2] ,
+\&...,
+.IB a [ n ] ,
+and returns
+.IR n .
+The separation is done with the regular expression
+.I fs
+or with the field separator
+.B FS
+if
+.I fs
+is not given.
+An empty string as field separator splits the string
+into one array element per character.
+.TP
+.BI sub( r , " t" , " s\fB)
+substitutes
+.I t
+for the first occurrence of the regular expression
+.I r
+in the string
+.IR s .
+If
+.I s
+is not given,
+.B $0
+is used.
+.TP
+.B gsub
+same as
+.B sub
+except that all occurrences of the regular expression
+are replaced;
+.B sub
+and
+.B gsub
+return the number of replacements.
+.TP
+.BI sprintf( fmt , " expr" , " ...\fB )
+the string resulting from formatting
+.I expr ...
+according to the
+.IR printf (3)
+format
+.I fmt
+.TP
+.BI system( cmd )
+executes
+.I cmd
+and returns its exit status
+.TP
+.BI tolower( str )
+returns a copy of
+.I str
+with all upper-case characters translated to their
+corresponding lower-case equivalents.
+.TP
+.BI toupper( str )
+returns a copy of
+.I str
+with all lower-case characters translated to their
+corresponding upper-case equivalents.
+.PD
+.PP
+The ``function''
+.B getline
+sets
+.B $0
+to the next input record from the current input file;
+.B getline
+.BI < file
+sets
+.B $0
+to the next record from
+.IR file .
+.B getline
+.I x
+sets variable
+.I x
+instead.
+Finally,
+.IB cmd " | getline
+pipes the output of
+.I cmd
+into
+.BR getline ;
+each call of
+.B getline
+returns the next line of output from
+.IR cmd .
+In all cases,
+.B getline
+returns 1 for a successful input,
+0 for end of file, and \-1 for an error.
+.PP
+Patterns are arbitrary Boolean combinations
+(with
+.BR "! || &&" )
+of regular expressions and
+relational expressions.
+Regular expressions are as in
+.IR egrep ;
+see
+.IR grep (1).
+Isolated regular expressions
+in a pattern apply to the entire line.
+Regular expressions may also occur in
+relational expressions, using the operators
+.BR ~
+and
+.BR !~ .
+.BI / re /
+is a constant regular expression;
+any string (constant or variable) may be used
+as a regular expression, except in the position of an isolated regular expression
+in a pattern.
+.PP
+A pattern may consist of two patterns separated by a comma;
+in this case, the action is performed for all lines
+from an occurrence of the first pattern
+though an occurrence of the second.
+.PP
+A relational expression is one of the following:
+.IP
+.I expression matchop regular-expression
+.br
+.I expression relop expression
+.br
+.IB expression " in " array-name
+.br
+.BI ( expr , expr,... ") in " array-name
+.PP
+where a relop is any of the six relational operators in C,
+and a matchop is either
+.B ~
+(matches)
+or
+.B !~
+(does not match).
+A conditional is an arithmetic expression,
+a relational expression,
+or a Boolean combination
+of these.
+.PP
+The special patterns
+.B BEGIN
+and
+.B END
+may be used to capture control before the first input line is read
+and after the last.
+.B BEGIN
+and
+.B END
+do not combine with other patterns.
+.PP
+Variable names with special meanings:
+.TF FILENAME
+.TP
+.B CONVFMT
+conversion format used when converting numbers
+(default
+.BR "%.6g" )
+.TP
+.B FS
+regular expression used to separate fields; also settable
+by option
+.BI \-F fs.
+.TP
+.BR NF
+number of fields in the current record
+.TP
+.B NR
+ordinal number of the current record
+.TP
+.B FNR
+ordinal number of the current record in the current file
+.TP
+.B FILENAME
+the name of the current input file
+.TP
+.B RS
+input record separator (default newline)
+.TP
+.B OFS
+output field separator (default blank)
+.TP
+.B ORS
+output record separator (default newline)
+.TP
+.B OFMT
+output format for numbers (default
+.BR "%.6g" )
+.TP
+.B SUBSEP
+separates multiple subscripts (default 034)
+.TP
+.B ARGC
+argument count, assignable
+.TP
+.B ARGV
+argument array, assignable;
+non-null members are taken as filenames
+.TP
+.B ENVIRON
+array of environment variables; subscripts are names.
+.PD
+.PP
+Functions may be defined (at the position of a pattern-action statement) thus:
+.IP
+.B
+function foo(a, b, c) { ...; return x }
+.PP
+Parameters are passed by value if scalar and by reference if array name;
+functions may be called recursively.
+Parameters are local to the function; all other variables are global.
+Thus local variables may be created by providing excess parameters in
+the function definition.
+.SH EXAMPLES
+.TP
+.EX
+length($0) > 72
+.EE
+Print lines longer than 72 characters.
+.TP
+.EX
+{ print $2, $1 }
+.EE
+Print first two fields in opposite order.
+.PP
+.EX
+BEGIN { FS = ",[ \et]*|[ \et]+" }
+ { print $2, $1 }
+.EE
+.ns
+.IP
+Same, with input fields separated by comma and/or blanks and tabs.
+.PP
+.EX
+.nf
+ { s += $1 }
+END { print "sum is", s, " average is", s/NR }
+.fi
+.EE
+.ns
+.IP
+Add up first column, print sum and average.
+.TP
+.EX
+/start/, /stop/
+.EE
+Print all lines between start/stop pairs.
+.PP
+.EX
+.nf
+BEGIN { # Simulate echo(1)
+ for (i = 1; i < ARGC; i++) printf "%s ", ARGV[i]
+ printf "\en"
+ exit }

+The scope rules for variables in functions are a botch;
