You can put a SET STEP ON in the code, and call the exe from VFP. As long as you have included debug info in your exe (project manager options).

>Second, if I run the code(again while only 1 instance is running) the records get marked for delete. I have set message boxes around each set of commands and nothing is skipped.

How about a messagebox that shows the DELETED() status of the record right after the DELETE command.
