I have an application that generates a form (MainScreen.Scx). The Main.prg includes

 Do Form MainScreen Name Main
Read Events

Included in the init method of MainScreen.Scx is

Do Main.mpx

I want to change the value (MainScreen.Label1.Caption) from a program called by the Menu prompt. (Either Command or Procedure) If this was "within" the form, the syntax would be:

Thisform.label1.Caption = 'New Caption'
Thisform.Refresh

But what is the syntax from MyPrg.prg called by Main.mpx

Thanks to all,

dg
