For a more complete description of ARexx, you'll have to dig up your manual. I'll only explain the necessary things. ProANSI's message port name is ``REXX_ProANSI'' (mind the case!), and all commands are explained in the `Command Reference' section. Please don't forget to turn on `OPTIONS RESULTS' if you want to have results. ARexx is a language which can best be learned by using it, so have fun!
