~~~ 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().
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.
Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.
