AHK - GetGlobal()

This is a simple function for manipulating a global variable in a function that doesn't have assume-global mode on.

GetGlobal(var,newval="£NO_NEW_VAL£")
{
   Global
   If (!RegExMatch(var,"^[a-zA-Z0-9#_@\$\?\[]]{1,254}$"))
      Return 0
   If (newval == "£NO_NEW_VAL£")
      Return % %Var%
   Else {
      %var% := newval
      Return 1
   }
}

Example:

FuBar = Hello World!
Message()

Message() {
   MsgBox % GetGlobal("FuBar")
}
