Please expand a bit on this.
What exactly do you mean?  Post your code (with the [code] tags) so that we can better understand your question.

Generally, use the GUI.Get... commands to get data about the widgets.  However, I'm sensing that this is not what you're asking.

As a guess, you could do something like this:

[code]
import GUI

var num1 : int := 0
% Variable to be changed by buttons.
var b1, b2 : int

proc b1proc
num1 += 1
% add to num1.
end b1proc

proc b2proc
GUI.Quit
end b2proc

b1 := GUI.CreateButton (100, 100, 20, "1", b1proc)
b2 := GUI.CreateButton (150, 100, 20, "X", b2proc)

loop
exit when GUI.ProcessEvent
end loop

put num1
[/code]


That would 'pass' a variable by the button to the outside...sorta...

what kind of variable are we talking about here? Button doesn't exactly have much info (well... atleast not in turing since nothing is exported and everything is constants anyways)

i want to load information from an array into a menu, then when the user clicks on a menu button it loads a proc that does something with the value of the menu button but i dont want to have 20 procs, one for each item.

Hmm...chances are that the you will need 20 procs...but you could cut down a bit using this:

- all buttons/menu items refer to one central proc
- for buttons, this will check their X/Y values (GUI.GetX...) and accordingly run a procedure.

Yeah...it doensn't do much.  Turing is like that, you'll probably need those 20 procs.

eh... does this help in any way?

proc something(num:int)
     put num
end something

var value:int := 5

b := GUI.CreateButton (100, 100, 20, "press me", something(value))

?
