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.
