1. Why won't my screen clear?
I am making a program that makes trivia games, when it's done, the last 3
lines are:
if graphics_mode(-1) then
end if
cursor(UNDERLINE_CURSOR)
abort(0)...
WHY WON"T IT CLEAR THE SCREEN? It just puts the DOS prompt at the currect
cursor location. Those last lines are in a procedure, does that matter?
Thanks

No.
I think you may have this confused with the system() call.
Graphics_mode(-1) changes back to the previous mode,
there's no mention of clearing the screen.
The documentation says that if it leaves junk on the screen,
you should use the DOS command CLS.
I think you could also put a clear_screen() right after the "then".

AFAIK, the screen will only clear the the graphics mode changes. If you
are already in text mode, the graphics mode won't change, and the screen
won't clear. That's been my experience.

Just insert clear_screen() right before the abort(0) statement.
The 'text screen' will be cleared and the cursor will be in the top left.=
