Is it unnecessary to declare a reference to a control variable in a function? Topic is solved

Hello,
Is it unnecessary to declare a reference to a control variable in a function?
I found that it works fine even if the control variable is not declared in the function.

Code: Select all

Gui, Add, Text, w50 vtext
Gui, Show, h100 w200
f()
return

f()
{
    ; Global text
    guicontrol,, text, xxxxxxxx
    return
}

You do not need to declare any variable.
The only variable that may need to be declared is whether you are creating an array or an object

ControlID in GuiControl, SubCommand, ControlID [, Value] accepts a string or a hwnd. it has nothing to do with variables.

when u do guicontrol,, text, xxxxxxxx ure passing literal strings to ControlID, its the same as doing the expression equivalent guicontrol,, % "text", xxxxxxxx

Thank you very much, it is for this reason.
