A couple days ago I asked some VT100 questions, and got these answers (thanks
folks) :

It means line 1-22.

Whole screen.

It is a VT52 "Exit HOLD SCREEN mode".  I don't know what a HOLD SCREEN mode
is, but that's apparently what the coe is.

Thanks again to those helpful folks who answered my questions.

Frank.
