The system function can be used to run UNIX commands from within XLISP-STAT. This function takes a shell command string as its argument and returns the shell exit code for the command. For example, you can print the date using the UNIX date command:
> (system "date") Wed Jul 19 11:06:53 CDT 1989 0 >The return value is 0, indicating successful completion of the UNIX command.
