I have an old alternate version of a form in VFP6 which had some modifictions made in 2001. I need to merge those changes into the current VFP9 version of the form. In effect at run time, the form now has to either do the current version of the logic, or the old alternate version depending on the customer.

I've manually made most of the changes by adding some if/then/else and some copy and pasting, but I'm not convinced I have everything correct.

Is there some way of getting all the custom methods of the form frome each version and running them throuigh some kinds of coapare?
