It's just that I remember the book that I have (Abacus, St internals Volume 3) saying that the screen is a VT52 when using standard output functions, such as printf (in C). And infact a small application that I wrote used a reasonable number of VT52 control codes with great success, however I admit that I didn't try screen regions, although if the screen is true VT52 then I see no reason why it shouldn't work. I have a (completish !?) list of VT52 control codes from an official DEC training course that I don't mind breaking the copyright on :-) if anyone would like me to type it in. The VT52 control codes for those that don't know are a standard set of ways of controlling the screen curser, including such wonders as directional control, display codes (inverse, bold, flashing etc) and scroll or no scroll regions. Perhaps I'm being a bit simplistic, but it seems to me that the above would quite easily solve the problem of creating a non-scrolling region. Hope this helps you, and if I receive enough Emails then I'll post to the net.
