In detail, yes. In general, please note the advice in
the Statalist FAQ
"The current version of Stata is 8. Please specify if you are
using an earlier version; otherwise, the answer to your
question is likely to refer to commands or features
unavailable to you."
In particular, the description yielded by
. ssc inst levels
explains that -levels- is for Stata 8, and that -levels7-
is available for Stata 7. So just substitute -levels7-
for -levels-.
Alternatively, of course, go for the more attractive
-merge- approach suggested by Nick Winter.
