Subject:VED in VT100 mode 
From:Jocelyn Paine 
Volume-ID:970507.02 

I've been having problems running VED on our Dec Alpha on the so-called
VT100-compatible terminal emulators. I sometimes find that although, when
it's first started up, the display is fine, scrolling gets the screen
image out of sync with the buffer. Quite often, the status line will be
overwritten by the first line of the buffer, or the line at the bottom
of the buffer will appear twice on the screen.

I had similar problems many years ago when running VED on some of our 
VT100 terminals, and the cause then turned out to be that it was not
quite adhering to the VT100 standard: I think it was failing to emit
a semicolon in one of the control sequences, or a second half of some
control code just after this semicolon. I wonder whether this bug
persists, and is now upsetting our emulators. Has anyone else experienced
similar difficulties?
