st: subscripts for loop?

[Kenley Barrett <k-barrett@northwestern.edu>]

I'm stumped on a programming problem. I need to refer to a sequence of 
variables b0_01, b0_02, b0_03 . . .  b0_18, where the subscript identifies 
an individual child of a given
woman and the first part of the variable refers to some characteristic of
that child. (The woman is the unit of observation, and for each woman
there are up to 18 children observed.) My idea was to do a loop with j=1,
then j = j+1, etc., referring to b0_j. But this won't work. My boyfriend
suggested doing the j loop and then concatenating to b0_, but I can't
find anything in stata on how to concatenate a number to a string.
Does anyone have any ideas?

Thanks for your help!
Kenley
