   Sounds like what you might need is the "File Exists" XFCN. As the name
   suggests it tests whether or not a file exists given a full pathname.
   You could then quizz the user in Hypertalk as to whether or not they 
   want to overwrite the file and use one of the various "delete file"
   XCMD's if they do, or just automatically add a "1" to the name otherwise.
   "FileExists" is a part of the Support Tools eXternals 1.2.5 package
   which (I think?) is available on apple.com.

I don't think this XFCN is necessary in HC 2.0 -- you should be able to say:

    if there is a stack "blah" then
     ...
