Pardon me, but if you know the name of your variable already, then it
seems that you don't really have a problem. If you know the variable
name is MOVIE, then why not hardcode that into the output string?
On the other hand, if you are in a procedure or function, it might
indeed be useful to know the name of variable at the *caller's* level.
In that case you would want to use the ROUTINE_NAMES function, which
is unfortunately undocumented.
I have documented what I and the newsgroup have discovered about this
very useful function. You will find it here:

listed under Introspection.
Good luck!
