procedure inside a procedure?

-----------------------------------

when creating buttons, i can create a button fine, and can get this to go to a new page, but whenever i try to create a button on that new page, it says "procedure's may only be declared at the program, module, or monitor level" How do you get around this?

For example :
(this is when it screws up)

import GUI
var mainbutton, pepsibutton, starPic : int
procedure maincourses
    cls
    var font4 : int
    font4 := Font.New ("BinnerD:16")
    assert font4 > 0
    Font.Draw ("What would you like?", 240, 450, font4, blue)
    Font.Free (font4)

    procedure pepsi
        put "Pepsi"
    end pepsi

end maincourses

mainbutton := GUI.CreatePictureButton (50, 50, starPic, maincourses)

pepsibutton := GUI.CreatePictureButton (275, 150, starPic, pepsi)

You simply don't put procedures inside other procedures.

-----------------------------------

That doesn't actually require you to have procedures inside of other procedures. A button can point to any procedure within its scope.

Are you learning procedures and GUI by yourself? Or did your teacher go through this with you?

-----------------------------------

basically just by myself..

and tony, i think i get what you're saying, but won't that just display all of the buttons on a single page?

im trying to have : once a button is clicked, a new page with more buttons is available

RE:procedure inside a procedure?

-----------------------------------

you can create buttons inside procedures, but the procedure that the button links to can be elsewhere.

You can also enable/disable/hide buttons so that only the right content appears on each "page"
