I'm working on porting some software over to the macintosh. Most of the port should be fairly straightworward - but the program needs to be interruptable. For various reasons, I don't want to throw in calls everywhere to check to see if keystrokes have been pressed, which is what would seem the natural thing to do - I don't have the time to go and rewrite the whole thing, I just need a quick and dirty solution. The only bona-fide interrupt that I could think of is the programmer's switch. Unfortunately, I couldn't find any help in Inside Mac as to how to intercept that. So could people send me information on how to do that, how tricky it would be, what registers, etc. would get nuked by it, where I could find more info (Tech notes, etc.), alternate suggestions, etc.? I'm using Think C 4.0 and a Mac SE/30, though I would like it to work on other macs as well. Many thanks, david carlton carlton@husc9.harvard.edu
