Re: st: Re: memory size 7 data merging

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.
