st: Re: Retrieving a master dataset after merging

["Michael Blasnik" <michael.blasnik@verizon.net>]

Well, I don't think you should ever save the new merged dataset on top of 
the master (i.e., don't use -save, replace-).  If you follow this advice 
then you could just -use master-.  Assuming you didn't follow this advice, 
you can retrieve the master dataset (if you didn't specify -update- as an 
option).  Just type:

keep if _merge==1 | _merge==3
drop _merge

if the using dataset contains some variables not in the master dataset, you 
then drop those:

drop usingvar1 usingvar2 usingvar3...
