Recently, I tried to set up a custom display list which did the
following:
two lines text (gr.0)
blank scan line + interrupt
several lines text + interrupt at end
LMS to new text line + horizontal scrolling enable
LMS back to final line
wait for VBLANK
Problem: after the line with horizontal scrolling enabled, the
DL stopped processing. The last text line was not generated. I tried tweaking
other things, and got garbage after the line with horizontal scrolling.
I finally got it to work by dividing the last LMS line into an LMS with
a blank scan line and then a text mode line.
Can anyone tell me why this won't work normally? I don't want to
have to put that blank scan line in there if there is any way around it.
Also: could anyone direct me to an ftp site when an electronic copy
of De Re Atari could be found? I have heard of this being on some commercial
service, but I don't have accounts on any of those.
Thanks in advance!
