I don't know enough of Delphi to know to accept a parameter in it, but to pass a parameter from Delphi to VFP, you need to call the VFP application with the parameter after the name (RUN MyApp.EXE MyParameter).

In your main application, you need to add LPARAMETERS MyParameter on the first line.

>How can I access parameter which is passed by Delphi exe. to a VFP exe or how can I pass parameter from VFP to Delphi ?
