NAME
icont - translate Icon program
SYNOPSIS
icont [ option ... ] file ... [ -x arg ... ]
DESCRIPTION
Icont translates and links programs written in the Icon language.
Translation produces ucode files, suffixed .u1 and .u2, which are
linked to produce executable files. Icon executables are shell scripts
containing binary data; this data is interpreted by iconx, which must
be present at execution time.
File names ending in .icn are Icon source files; the .icn suffix may be
omitted from command arguments. An argument of - reads from standard
input. A name ending in .u, .u1, or .u2 selects both files of a ucode
pair. The specified files are combined to produce a single program,
which is named by removing the suffix from the first input file.
An argument of -x may appear after the file arguments to execute the
linked program. Any subsequent arguments are passed to the program.
Ucode files produced by translation are normally deleted after linking.
If the -c option is given, processing stops after translation and the
ucode files are left behind. A directory of such files functions as a
linkable library.
OPTIONS
The following options are recognized by icont:
-c Stop after producing ucode files.
-f s
Enable full string invocation by preserving unreferenced procedures
during linking.
-o file
Write the executable program to the specified file.
-s Suppress informative messages during translation and linking.
-t Activate runtime tracing by arranging for &trace to have an initial
value of -1 upon execution.
-u Diagnose undeclared identifiers.
-v i
Set verbosity level of informative messages to i.
-E Direct the results of preprocessing to standard output and inhibit
further processing.
-N Don't embed iconx path in executable file.
-V Announce version and configuration information on standard error.
TRANSLATION ENVIRONMENT
Two environment variables control file search paths during translation
and linking. These variables contain blank- or colon-separated lists
of directories to be searched after the current directory and before
the standard library.
IPATH
Directories to search for for ucode files specified in link direc-
tives and on the command line.
LPATH
Directories to search for source files specified in preprocessor
$include directives.
EXECUTION ENVIRONMENT
Several environment variables control the execution of an Icon program.
Values in parentheses are the default values.
BLKSIZE (500000)
The initial size, in bytes, of the allocated block region.
COEXPSIZE (2000)
The size, in words, of each co-expression stack.
ICONCORE
If set, a core dump is produced for error termination.
ICONX
The location of iconx, the icon interpreter, overriding the value
built into the executable by icont. Not required if the configura-
tion is unchanged since build time or if iconx is in the same
directory as the executable.
MSTKSIZE (10000)
The size, in words, of the main interpreter stack for icont.
NOERRBUF
By default, &errout is buffered. If this variable is set, &errout
is not buffered.
QLSIZE (5000)
The size, in bytes, of the region used for pointers to strings dur-
ing garbage collection.
STRSIZE (500000)
The initial size, in bytes, of the string space.
TRACE
The initial value of &trace. If this variable has a value, it
overrides the translation-time -t option.

CAVEATS
Icon executables are not self-sufficient, but require the iconx inter-
preter. When distributing an Icon program in executable form, include
a copy of iconx in the same directory.
