RE: dRE: No Subroutines (was Re: Debugging many subprocedures)

Duane,

Your post would be more useful if you included the original example, and
your ideas for improvement. As it is, I have no idea what specific code
you're referring to. Is it the procedure that validates data, or the
subroutine within a procedure that validates the input parms?
