[comp.lang.pascal] Reading in two characters from the keyboard

ALG106@PSUVM.BITNET (04/13/89)

I am writing a program in Turbo Pascal and I need to know when two keys are
pressed simultaneously.

Specifically, I need to know if while the up arrow is being held down, if
a number key, or a function key (F1 - F10) is hit and then released.

If there is a way to check for the release scan code of the arrow key, and
the scan code of the function key, it would work.  I can get the scan code of
function key, and the scan code of the arrow.  I cannot get the scan code for
when a key is released.

Any suggestions would be helpful.
                          Thanks,
                              Andy
