I'm struggling with AppleScript,  basically I just want to make my own "keep

(which works), I want to check it isn't already running.   I can get the
name of every process in AppleScript, or even the creator type, but how do I
pass that information back to revolution?   In Hypercard Applescript could

Or is there a better way to get the running processes?  Hypercard I could
just check the contents on the "application" menu!  Can I do similar in
