Hi Chris,

After you've followed Erik's and Phillip's suggestions and you have some asm code that will assemble and run, then the *real* fun begins, modifying the code with descriptive labels and comments so you will have a good source capable of being modified safely.

If your original was compiler generatated or produced by a skilled assembler programmer who was fond of tricky coding, deciphering what each function is doing and why can be pretty challenging.

Good luck!

Dennis
