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...

Dear All,
After doing a -merge-, can one retrieve the master dataset? If yes, how can it be done? Thank you.
