Scrolling: Bottom Line Not Overwritten #85

Closed OzHawk closed 2 months ago

OzHawk commented 2 years ago

When scrolling a long program listing up and then down (or down and then up...depends on perspective) the bottom line is not overwritten. Once the bottom line contains text, it seems to remain there. edit does not clear it. cls clears the bottom line.

It appears that the bottom line is populated when scrolling up, but not when scrolling down.

It may be caused by the fact that the bottom line is not a whole 8 pixels high.

phys_mode=4 csize(0) = 80 csize(1) = 33 psize(0) = 480 psize(1) = 270 psize(2) = 540
