I am no mata expert, all I can tell you is what I found
in the helpfiles:
I don't think it is necessary to loop here: 
-help mf_st_addvar- tells me you can create multiple 
variables in one go and -help mf_st_store- tells me you 
can store a matrix.
 
I forwarded this answer to the statalist in case there 
is a mata expert listening and willing to check or 
elaborate my answer.
 
Hope this helps,
Maarten
