GUI Pop up windows

[Pwah]

aparently there is a way when you click on a gui button it opens the procedure in its own window.
if so how do you do it?
I want to be able to open it and when you clise it or click a button it runs a main screen again

just have the first line in the procedure be a Window.Open call. The procedure will open a new window whenever called and run itself in that window.

I have been messing around with GUI.HideWindow and i added my own little throw together calculator to it

code:

% The "GUI.ShowWindow" program. import GUI var windowA, windowB : int var buttonA, buttonB, buttonQuit, backToMainA, backToMainB : int var cal1, cal2, answer : int var i : string procedure calculator put "Input First Number:"     get cal1     put skip     put "Input Second Number:"     get cal2     put skip     put "Input Method: (+, -, x)"     get i     if i = "+" then         answer := cal1 + cal2     elsif i = "-" then         answer := cal1 - cal2     elsif i = "x" then         answer := cal1 * cal2     end if     put skip     put "Answer:"     put answer     put skip end calculator procedure WindowA     GUI.HideWindow (defWinID)     GUI.ShowWindow (windowA) end WindowA procedure WindowB     GUI.HideWindow (defWinID)     GUI.ShowWindow (windowB) end WindowB procedure BackToMain     GUI.HideWindow (Window.GetActive)     GUI.ShowWindow (defWinID) end BackToMain View.Set ("graphics:280;100,nobuttonbar") % Place the buttons in the main window buttonA := GUI.CreateButton (10, 10, 0, "Show Window A", WindowA) buttonB := GUI.CreateButton (150, 10, 0, "Show Window B", WindowB) buttonQuit := GUI.CreateButton (100, 60, 0, "Quit", GUI.Quit) windowA := Window.Open ("title:Window A,graphics:500;500") calculator backToMainA := GUI.CreateButton (20, 20, 0, "Back to Main", BackToMain) Window.Hide (windowA) windowB := Window.Open ("title:Window B,graphics:150;100,position:bottom;right") backToMainB := GUI.CreateButton (20, 20, 0, "Back to Main", BackToMain) Window.Hide (windowB) loop     exit when GUI.ProcessEvent end loop

and it opens the window first (only when needing input tho)
what am I doing wrong or am i using the wring thing?
