Hi Hans

>I faintly remember there has been a tool which allows comparing the definitions of the variables at the beginning of program/Subroutine/Function with what is used in the code later on.

Npt used tested, only saved the link: foxmasters.com. Also I believe right here in the DL section is a simple version of such a tool. If you work with one or both, pls. post your findings - sure a long way around to communicate<g>.
