~~~ Design Notes ~~~

This is part of a series of SET functions:
SetVar and SetField

These are all designed to work with variables and to
keep the variables from being un-set (removed from memory),
by using the string "Empty" to indicate IsEmpty().

Example:
If a field, MyField, is empty and I use SetVar(),
MyVariable = SetVar( MyField )
Tnen MyVariable is now = "Empty".

These are related to a series of LIST functions.
ListAdd, ListAddUnique, ListExist, ListGet, ListToggle.

Which are designed to work with variables and the "Empty" idea.
