Does Applescript work?

Having struggled with AppleScript for many years, I have a few pieces of

Firstly, always write & debug in an AppleScript editor before transferring
the script to HyperCard or Rev.

Secondly, do the bare minimum in AppleScript and do as much as you can in
xTalk - it is faster to run and easier to program & debug.

With your list of processes, I used the following technique:

I copied this script into a field:
    tell application "Finder"
        return every process
    end tell

Then I had a button with this script:
    on mouseUp
      do fld "AppleScript1" as AppleScript
      -- now get what the AppleScript returned
      put the result into processList
      -- now do your stuff
    end mouseUp

I prefer to use a field rather than assembling the script in a Rev script
because it is much easier to catch any errors and to edit later. You can
hide the field once you have it working properly. If there is any chance of
the AppleScript failing, use a "try" construct and return the error to your
Rev script.
