Well, dumb me, in the comments, which I didn't pay enough attention to, it says it's a function in SBTTools.FLL. That just makes it more of a pain to modify this. What's the point of supplying source, when they put functions like this that determine the price of the item into a C library?
>Not sure I'd bet this is a Process Pro program. Have you used the code references tool in VFP to search for it?
