According to the help manual, this is how global and local variables relate
to functions (depends on where they are first defined):
If given identifier appears first INSIDE function definition - then it is
treated as LOCAL variable.
If given identifier appears first OUTSIDE function definition - then it is
treated as GLOBAL variable.
