I have an application that uses the DEC Screen Management Routines (SMG). It uses a screen sized pasteboard and virtual display. The only output is made with SMG$Put_With_Scroll and input echoing as a result of input through SM$Read_Composed_Line. All works well except when run from VT52 terminals (Don't laugh, some of us poor souls still have a lot of these things). SMG scrolls VT52 terminals by refreshing the entire screen! Needless to say this takes a bit of time and is not acceptable. I know that some DEC utilities use SMG without experiencing this problem but can't figure out how they do it. Anyone else have any guesses?
