Can somebody give me a few pointers of how %% to go about this ? I use Microsoft C 6.0A and would appreciate if someone could %% tell me how to go about in MS-C. Some years ago I needed to drive the PC speaker in assembly, so I took Turbo Pascal (3.0!), wrote a simple program using the Sound and Nosound calls (I hope the names are right), compiled it, then disassembled using DOS debug. Now with the symbolic possibilities of modern debuggers you only need a couple of minutes to get a listing of these routines. Why didn't uSoft provide them? (didn't they really?) Good luck!
