For simple stuff, you can look at the 'current-command-line-arguments' parameter, which is a vector of the passed arguments. http://docs.racket-lang.org/reference/runtime.html#%28def._%28%28quote._~23~25kernel%29._current-command-line-arguments%29%29 For example: ;;;;;;;;;;;;;;;;;;;;; #lang racket (printf "The current command line arguments I see are: ~s" (current-command-line-arguments)) ;;;;;;;;;;;;;;;;;;;;; should show that you get back the arguments as a vector of strings. If you want to do something more sophisticated in terms of command line argument processing, you may want to look at the racket/cmdline library: http://docs.racket-lang.org/reference/Command-Line_Parsing.html where it handles things like handling switches and optional parameters. It also generates a "--help" command for you. I hope this helps! ____________________ Racket Users list: http://lists.racket-lang.org/users
