To help me (and others...?) get things straight, I've seen some scripts
(Paul B, I think) that use something like:
property myvar : missing value
In what way should we be using that as an initial value, and what is the
logical operator for comparison of that variable?
if myvar = missing value -- this?
if myvar = "missing value" -- proably not
if myvar is undefined -- whoa
Throw us a bone here, someone.
