st: Looping gen sequentially over datasets

["Alex Sutherland" <as2140@cam.ac.uk>]

Dear Statalisters,

I am trying to generate sequential ID variables over a series of datasets.
There are 40 datasets representing 40 schools and I want to generate an ID
variable for each school (ranging from 1-40) without the need to open and
edit each file manually. (I'm likely to have to repeat this process later
and I want to combine the datasets once the ID variable is created, hence
the need for unique identifiers for each school). I keep thinking it's going
to involve a foreach loop over the datasets combined with another loop
(forval?), but then I'm up against the limits of my Stata-ing so any help
gratefully received.

Thanks in advance,

Alex
