There are probably other ways, but personally I keep Stata 7, 8, 9 
and 10 installed on my machine.  I don't know about Mata, but in ado 
files version commands don't guarantee that your code will work with 
older versions of Stata; rather, they guarantee that your code will 
continue to work right with future versions of Stata.  e.g. if my 
code says -version 9.2-, a new 10.1 command will still work in Stata 
10.1 but won't work in Stata 9.2.

So in general, if you want to be sure something will work right with 
an earlier version of Stata, it is best to write or at least test it 
with that version of Stata.  At least that is true for ado files - 
perhaps it is different for Mata.
