Silly Scribble Program

Ad asked for conversion of David's scribble program
to "dos", using any library of choice...

below is my answer to that 'challenge'...
it reads as easy (if not easier) as the original
winsnorz program, and doesn't require the 80 or more
megs of winsnorz *bloat*... :)

side note: since the latest update of TrueEU affects
   confined mouse work, it's best to use that latest
   version of TruMouse/TrueEU with this program...
   I'm not sure how an older version of TrueEU would
   behave while running this scribble program...

enjoy! --Hawke'
