Disabling Buttons After Use

Im kinda still a newbie to turing ......

I wanted to know how to disable a button after it is pressed since you can't put the disable button command in the procedure itself.

What im asking.. is there an alternate way of disabling a button since the disable command has to be after the button is created and the procedure comes before the button.

Use an array of boolean. Similarly to input. Set all the values to true with a for loop, and as the conditions are met set the key to false. There is probably a more elegant way of doing this. Just an Example.
code:

var KeyOn : array char of boolean
var KeyInput : array char of boolean

for i : 1 .. upper (KeyOn)
    KeyOn (chr(i)) := true
end for

loop
    Input.KeyDown (KeyInput)
    if KeyInput ('w') and KeyOn ('w') then
        put "After all this suff is done disable the key"
        KeyOn ('w') := false
    end if
end loop

I dont understand arrays yet

and I was talking about a ------>GUI.CreateButton<------- not a key on your keyboard

Ah I see, I avoided GUI, sorry I can't help you there.

Styles you should learn arrays before you move to any GUI.

I don't really understand what you are asking. Maybe if you posted some pseudo-code to show what you are attempting, you can get better help.

you cannot disable something when its not there, so im not sure why are you trying to disable your button before it even existed.... and for disabling button, you can just simply do something like
code:
GUI.disable(my_button_name)
and it will be gone for good

how about a boolean varible set to true when activated so...

code:
var buttonPressed:boolean:=false

proc thing
    buttonPressed:=true
end thing

loop
    exit when GUI
    if buttonPressed then
        delete button
    end if
end loop

Since Turing's built in GUI uses action procedures, you can simply have your GUI.Disable() as the first line in your procedure so that you don't have need for a silly boolean variable to keep track of as well.
