Mac is looking for a way to allow two users to use keypresses at the same time. Perhaps some assembly code?

Yes, he resorted to that, but I was thinking there could be an Interrupt routine to eliminate all of the Assembly code strings using Absolute.
Naturally, Mac needs Absolute for Qbasic to work it.
Thanks,

I've for some reason never taken the time to analyse that assembly code, but I presume it installs a new handler for when a key is pressed on the keyboard.
I can think of no way of doing it that would be as reliable. I'm fairly sure there's no DOS or BIOS interrupt that will provide the same functionality.
If the fact that Ctrl+Break doesn't work is a problem (or something similar), then that is an issue which can be solved with some work.

Well, if it can be done with Absolute, then it should also be possible in an Interrupt routine. The big question is how to avoid messing up the keyboard entries if you do not exit it correctly.

Well, if it can be done with Absolute, then it should also be possible in an Interrupt routine. If you mean do it purely using CALL INTERRUPT, then no, that is impossible. Just because ABSOLUTE can be used to initiate an interrupt, doesn't mean INTERRUPT can be used to replace an ABSOLUTE routine. They are not two different angles on the same thing. |
