I did try to drop the other variables from the epo.dta dataset before
attempting the join.  However, the memory issue remains.  I'm basically
trying to join a 3 variable dataset (hgb.dta) of 7,438,632 records and
255,317 unique ids with a 2 variable dataset (epo.dta) of 406,400
records and 36,381 unique ids.  Maybe this is beyond the capabilities of
Stata.  Any other suggestions would be welcome.  would doing a
many-to-many merge result in the same dataset (all pairwise
combinations)?
