Good point. If the cursor is on while you call the PLOT routine, it sometimes gets caught by the interrupt, causing some screen locations visited by the cursor
to switch to reverse video.
You will need a short ML routine that turns off the interrupt, corrects the cursor if necessary, calls PLOT and then turns the interrupt back on.
I have something like that lying around. If I can find it, I will post it.
Thanks for the tip on the status register (location 784). My Programmer's Reference Guide lists it as "SP" which I took to mean stack pointer. Should have known.
