Now when I look at the output with DOSBOX running at 6000 clock cycles, the execution is slowish where I really notice the flicker when the screen clears.
Code: Select all
for n% = 1 to 15 locate n%,1 print space$(80) next n%
I might have to roll out a fast assembly routine, unless someone knows how to clear half a screen much faster.
The reason why I need to do this is because I am making a live data logger and I need to see the data at a certain section of the screen, and without clearing part of the screen, I'll see incorrect (old data) as the amount of fresh data varies every time.
