Well nothing kills like overkill...if you've determined the model the screen character data is always maintained in RAM at the same spot per model (as opposed to the raster which is only maintained in the display drivers). Using varptr peek and poke you could create a special 40 character string that points to the last line. Once you've done that you can use regular string and print routines to save / restore it which would be very fast.
Though I am becoming intrigued... I'd have thought the label line would be saved and restored by the interpreter. If it isn't there must be some way to hook the event so that the program can repair the display when the user pops it back down. -- John.
