Right,
I know how I use and depend on it working in other languages, and
am glad to see that it works as I would expect.

I believe it's called, 'short-circuit evaluation', and applies to
binary operators like AND and OR. i.e. If you have two expressions
that evaluate to the Boolean data type, and you're using them like
If <expr1> AND <expr2> Then
the computer will check <expr1> first and - if false - won't bother
to check <expr2>. This is handy if <expr2> involves an object
reference, then <expr1> can test for the reference <> nil, thus
saving you from a NilObjectException in <expr2>
