Thanks Alex (or Al).

Breaking out of old global variable ways is going to be interesting.
What an interesting way to handle global variables.

Is there a way to require variable pre-declarations? Where the
parsing unit throws up an error if a variable is not predeclared?

For instance, the .asp ways and means...

Option Explicit
Dim sCounterFile
sCounterFile = "counter.txt"

Thanks for explaining "global" and "GLOBALS[]".
