Hi Fred,

> have the ability to breakpoint on the use of a VFP command. Not just on a particular line of code with the command, but on use of the command period.

Somehow this is possible, I just don't know how. Y2KFOX from Netlib is such a product that alters the behavior of native functions like CTOD(). My bet would be that there's a list in memory that maps every token to a C routine to execute it. Changing that list would execute different code.
