Is there any way to limit the text output of TOS to a section of the screen instead of the whole screen so that printing, scroLling, etc just happens inside that section? If this can be done, we can put a TOS text window inside a GEM window and by calling TOS routines instead of VDI scrolling of text can be much faster. Of course, this may mean that we have to limit the boundary of windows to be on the multiple of 8 pixels.

If you carefully read SALAD, analyze the Line-A variables (especially the ones at negative offsets from the line-A variable base pointer, which were previously undocumented), and experiment some, you will find that you CAN do this. The code is parameterized enough that this kind of thing is possible. You will still have to take care of clipping and redrawing... Read carefully and experiment, and especially experiment with accessories like the control panel active on the screen, to see if you got redraws working correctly. ============================================ Opinions expressed above do not necessarily -- Allan Pratt, Atari Corp. reflect those of Atari Corp. or anyone else. ...ames!atari!apratt
