>When I run a VFP 6.0 form I want to have a command button on the form that runs a FP 2.6 for Windows executable (the executeable runs data entry forms). Is there a way to pass the parameters from the VFP 6.0 form to the FP 2.6 executeable so the values get passed from form-to-form?

Use the RUN command and specify parameters. You can't pass values back or anyhting though, the way to do that would be with thet Table method. You might have better luck with COPY TO .. TYPE FOX2 or whatever it is than just using VFP tables in FPW.
