tabulate the _merge variable after using the nokeep option and you can just look at the resulting number of observations to calculate how many _merge==2 observations there would have been (at least if you aren't doing a many-to-many merge, which you shouldn't be). Obviously the nokeep option will be of little help if there would be few _merge==2 observations.

With -nokeep-, would you need to sacrifice any -assert _merge == 3-
and -assert inlist(_merge, 1, 3)-?  I would dread not being able to take
advantage of -assert- after a -merge- with the datasets that I get handed.
