The PROED.TTP program has been compressed.
It will decompress itself automatically when it runs.

The way to exit from the editor is a bit obscure, you need to...
  hit <F10>
  type "QS" (Quit and Save)
  hit <Return>
  hit <Return> again
  hit <Esc>

or use "QA" (Quit and Abort) if you don't want to save the file.

It has online help - hit the <Help> key.
