where are values in functions submitted with return stored? Topic is solved

[wryyymuda]

in this function

Code: Select all

AnyPressedKey() {
Loop 256
if GetKeyState(Format("vk{:x}", A_Index-1),"P")
return GetKeyName(Format("vk{:x}",A_Index-1))
return 0
}

where is the 0 returned too? how would I use it, what variable would i

It's returned as a result of the function call, which you can assign to a variable such as:

Code: Select all

Key := AnyPressedKey()

or use directly such as:

Code: Select all

MsgBox, % "Pressed key: " AnyPressedKey()
