I assume James is running Sean Reardon's -hlm- command available from 
SSC; if not he needs to make that clear. The help says "These 
commands allow the user to invoke and run HLM v6 from within Stata 
8.2 or higher." (HLM V6 being some other company's software.) My 
guess is that James is having trouble because Stata creates a bunch 
of .dta files that then get used by HLM, but I don't think HLM can 
read Stata 12 files. The -hlm- help also says the path for HLM needs 
to be specified correctly, so James might check and make sure he has 
that right.

It looks to me like -hlm- handles version control correctly, but it 
is still at the mercy of changes in Stata or HLM made after -hlm- was written.

James might also take a look at Stata 12's -sem- module and see if it 
can do what he wants. HLM can probably do more, but -sem- might work 
depending on your needs.
