Local variables must not be declared in this function

[rengg]

Code: Select all

someClassMethod() {
	ControlGetPos, x, y,,, SomeControl
	local someVar := 5
}

If i declare/initialize the local variable before ControlGetPos then there is no error. Trying to figure out why.

Assume-global mode: If a function needs to access or create a large number of global variables, it can be defined to assume that all its variables are global (except its parameters) by making its first line either the word "global" or the declaration of a local variable.

[EDIT] Unless the first line of the function's body is, either the word "global" or the declaration of a local variable, your function behaves by default in a "assume-local mode" in such a way that declare your variable as local thereafter is superfluous; hence the "Local variables must not be declared in this function".

Variables defined within any function/method are local and won't be remembered when it ends. If You want it to be remembered between calls, use static this.variable (only for class instances).
