>Could anyone tell me how to pass a parameter when I run an .exe file ? I am getting an error when I used "do dummy with 'test'". Thanks

Put a LPARAMETERS statement at the top of your Main.PRG. Then you can run from FoxPro like what your doing, you can also run from teh Command Prompt or ShortCut with:

MyApp.EXE UPDATE

where "UPDATE" is teh parameter.
