>FWIW, I used to write functions in separate PRG files. It was in the 1980s with Multi-user FoxBASE+ when I first came to XBASE. But once I discovered procedures and functions ... I never looked back. And never will. :-) Truly amazing to me that people would seriously advocate such a thing.

Have to agree.
I definitely understand Mike's point and it's well taken, however we are humans, not computers.
That logic, taken to its end point, would mean that there would be no folders on a hard drive.
That would be the most efficient arrangement, but it would be unintelligible to humans.
