Mandy, if you know this much about each variable, I see no advantaqe
or necessity to your approach. -mvdecode- appears to be superior in
every way. It is not only more direct, clearer, and will handle
all the other "non-data" codes. Clarity is very important: other
people (and you, perhaps, in the future) will be able to understand
your Stata statements without any lengthy explanation. None of the
other solutions can claim that.
