UNIX Functions

With a UNIX/linux/Mac OS X command line version of Chipmunk Basic, the following commands are very powerful. Using them, Chipmunk Basic can be used to write shell scripts, control other programs, and do all manner of mischief.


When used in a Basic program file, upon load, sets the Chipmunk Basic interpreter to run-only mode, interactive mode disabled. The STOP and END commands and the use of Ctrl-C will quit the interpreter. Insert #!/basic along with this command as the first two lines of your program, chmod +x it, and you've got an executable script written in Chipmunk Basic!


UNIX system call. The string parameter is given to the shell as a command. Returns exit status.

getenv$( STRINGVAL )

Returns value for environment name STRINGVAL.


Returns the UNIX shell command line arguments. The first two are always "basic" and the name of the program file, at least under Mac OS X.
