Removes all global variables listed in $$GlobalVarList, including $$GlobalVarList. If used properly, this can insure a file has no Global variables in use any more.
NOTE: Should be used in conjunction with the CF "VariableInitialize ( name ; initialValue )", which maintains a list of all variables initialized in a file in another variable named $$GlobalVarList.

Forgive my ignorance, but I'm scratching my brain raw figuring out how to implement this (and its companion) custom function.
Let's say there are three global variables ($$_Alpha, $$_Bravo, $$_Charlie) that I want to null in a script using this technique. How do I set it up, not knowing what the variable's contents are (since they'll change as a loop function is called)?
TIA for your help.

This function only removes variables it knows about because their names live in a variable called $$GlobalVarList... Which is what the other companion function does, it creates the variable and logs it to that variable.
You could easily write a function that takes a list of variable names, as teext, and clears them all in one fell swoop. It would either be recursive, or substitute the evalates clearing similar to my functions.
A great custom funtiin is CustomList, Google it. It's tremendous, and does it's majic non recursively!!
