Jane,
If the form is going to receive command line parameters, you have to use a small .prg marked as Main in the project manager, that accepts the parameters and sends them onto the form. It's not so bad having a main .prg anyway even if it only does:
* MyApp.prg
do form MyApp
read events
This way you form doesn't have to be modal during development/testing and a form method can not put itself into a READ EVENTS state.
>Thanks for the reply but .. it doesn't work. I get the message "can't build without a main program." Do I need to create a main.prg that has a call to the screen? I'll try that.
