Parameters and Variables

[PuzzledGreatly]

Within a function parameters can't be variables but how to create a GUI variable inside a function without declaring the variable as global or static in advance? Is there anyway to pass a variable name into a function? Thanks.

Is this what you want?

Code: Select all

variablename := "x"
%variablename% := 5

test( variablename, x )

test( a, b )
{
    msgbox, % a " has the value " b
}

Parameters are variables.

I assume what you mean is that you cannot use parameters as GUI variables. That is because parameters are non-static local variables. You cannot use non-static local variables as GUI variables.

If the variable already exists as a static or global variable and not as a non-static local variable, you can just pass vvariablename to the Gui command without prior declaration. Otherwise, you must either explicitly declare the variable or make the function assume-global or assume-static.

Is there anyway to pass a variable name into a function?

Yes, the same ways that you pass any other string into a function...
