What you want to do is to have some system code that will
handle your writes to the CRT. When you detect that the
write is going to go onto line 25, you want to scroll lines
0-23 (INT 10H,AH=6) up and then move the cursor up a line so
that line 25 'appears' to be stationary. One simple way to
to use the WRITE TTY (INT 10H, AH=14H) to output the
character and then to look at the cursor position after the
call (so that all then normal processing is done).
