Hi Mark,
Wow! Thank you for this info! I built the CLR command and it works
flawlessly. I need to read up on Macro11.
I will definitely check out MCE. I tried something like that a while back
under M+, don't know if it was MCE or another one I had found.
Thanks!

Peter,
I also had the same problem when using RSX11M instead of M+.
Below is a quick Macro-11 program that sends two VT100 escape sequences.
The first clears the screen and the second sends the cursor home.
It can be easily modified for other terminal types if needed.
For command line editing that works with RSX11M, take a look at the
MCE command line editor.
It is a great DECUS program found on RSX SIG Tape Spring 1989 in [265,1]
Best,
Mark
