To the best of my knowledge no one has successfully
uncompiled/decompiled dBASE's .pro/.wfo/etc. files.
That was the point when the format was determined years ago. Otherwise a
dBASE developer could distribute a .pro to a customer, that customer
could decompile it back to source code, and modify the code ... thereby
making it possible for the original developer to lose
business/customers/intellectual property, and so on.
The difficulty then is that of course if you don't have the source code,
as I understand you don't, then the programs will need to be re-created
