When I executed a command like the following, I got an error indicating that 'File myproc.prg' does not exist.

USE BMAIN.DBF INDEX BMAINI.CDX ORDER NAME SHARED AGAIN

I included myproc in my program and the USE command now runs successfully.

What can make the USE command execute code in my program?
I looked for rules and triggers but do not see any associated with this table.

Thanks,
Howard
