  14. I'm trying to write my very first program on a Mac (except hello world)
  15. using Think C 5.0.2  & Think Reference.
  16. I'm fuddling along, and things are working alright if I'm stepping through
  17. in the debugger, but if I try to run the program without it, it crashes
  18. immediately.  Not even CMD-OPT-ESC saves.  I'd think I'm trashing system
  19. mem, but it does work fine with the debugger.
  20.  
  21. Code follows.  Please understand that this is my very first program
  22. attempting to use any procedures not my own.  The code is messy.  Bear with
  23. me.
