>>If, when using an APP file with the DO syntax, you do need a "main". This serves as the entry point for the application. You can pass parameters to it to further control what's done in the app.

Dmitry,

>Thank you for your helpful input. I realize that I can pass parameters to my APP and in my case I will probably do it via an array, since I have tons of parameters to pass. My only concern, so far, (since I have not implemented this APP) is how it will look. That is, when I have a bunch of windows open in my main application and one of the windows calls an APP program, will APP program "cover" all my main program windows with a new VFP main window. I guess I have to try and see.

First, you're welcome.

Second, may I suggest a form manager that will take care of this based on the parameters ou pass?
