Well, I'm trying to write a multi-segment program that would use the
Sound Manager heavily if it would stop crashing. I think that the problem
has something to do with where my callback procedure (for asynchronous sound)
is. In the sample code supplied by apple (soundapp), they put the callback
procedure in one unit, but put the actual procedure in a certain segment
using {$S main} in MPW (correct me if I get any of this wrong). Is there any
way to declare a procedure in a different segment than the rest of a unit in
Think Pascal? (is there any way to do a {$S main} in think P)
Also, if anyone has any experience in Multi-segment sound manager code in Thinl
Pascal, I woul love to hear from you.
Any help would be greatly appreciated, but please send to the following address
or post c.s.m.programmer if appropriate:

Leonard Rosenthol Software Ventures Heck, it made the porting of MacApp *possible*! Make sure you disable the debugger (with {$PUSH} {$D-} <...code...> {$POP}) for your Sound Manager callbacks. If an async callback is executed while debugging is on, Think Pascal will most likely crash. Of course, you are using the updated Sound Manager docs (J. Reekes, 1988), not the stuff in IM-V, right? -phil shapiro, symantec tech support -- Phil Shapiro phils@chaos.cs.brandeis.edu
