All,

 If there are any x86 programmers out there that are familiar with assembly
 language, I would appreciate you having a look at my delay routine and see
 if you see any obvious reason why it wouldn't work.

 If I use debug, it seems to work fine.   But if I try to let it run stand
 alone, it prints one 16 bit value on the screen, and then hangs.

 I don't understand why it isn't working.   If anyone can help, I'd 
 appreciate it very much.

 Please advise off line to jim@jpes.com


                                                 Thanks and Regards,

                                                        Jim

between one time and three times.
