  21. ;    ScreenFKEY is a basic example on how to spool a PICT file to disk by replacing the 
  22. ;    bottleneck PutPICProc, it saves the contents of the screen to a file. The FKEY creates 
  23. ;    ten files Screen 0 through Screen 9; it is necessary to erase or rename old files when 
  24. ;    the limit is reached. 
  25. ;    
  26. ;    This FKEY works in any Macintosh computer and saves the screen regardless of the 
  27. ;    setting of the screen; to use, it has to be added to the System file using ResEdit.
