You could use a mix of -generate- and _n in order to achieve what you want.
However, I would think it could be better (considering that you are
studying cohorts) to use the -tsfill- command, which fills missing
observations in a panel.
See help tsfill, and remember that you must first -tsset- your data.
After using tsfill, count the number of missing values. If there are 0
missing values, then there are no gaps.

Hello - I was wondering whether there was any command for checking
for gaps in a given variable. In other words - supposing I have
"myvar" which is supposed to run from 1 to 256 consecutively. But
there may be gaps in this variable, and it might be missing, say, 69
and 78. Is there a command I can use to detect this sort of thing?
In case anyone is interested, a fuller context of the problem is that
I am creating synthetic cohorts from a series of random cross
sections, and one of the conditions is that there must be no empty
cohort. I wrote a do-file that takes my time-invariant parameters
(age, race and gender) and partitions the set of individuals across
each year. One of the conditions I would like to impose is that there
should be no empty partition, and I was wondering whether there might
be an easy way to check this condtion.)
Thanks!
