ICON(1)ICON(1)NAMEicon - execute Icon program
SYNOPSISicon sourcefile [ arg ... ]
icon-P 'program' [ arg ... ]
DESCRIPTION
Icon is a simple interface for executing programs written in the Icon
programming language. The source code is translated and linked, then
executed with the given list of arguments.
Without -P, a single source file is read; its name must be given
exactly and need not end in .icn. A sourcefile name of - reads the
source code from standard input.
With -P, a small program can be embedded within a larger shell script.
In this case the program argument is a complete Icon program, typically
given as a multi-line quoted string.
Translation and linking is silent, suppressing progress messages, and
undeclared identifiers are diagnosed. This mirrors the behavior of the
icont command when run with -s and -u options.
An Icon source file can be made directly executable by setting the
appropriate permission bits and beginning it with a shell header. If
the first line of the file is
#!/usr/bin/env icon
then icon is found on the command search path and called to process the
program upon execution.
ENVIRONMENT
The environment variables described under icont(1) can also be used
with the icon command. Normally, none of these are needed. The direc‐
tory containing sourcefile is searched first for any $include files.

multiple source files, and other features.
