Rereading my answer I think it may be misunderstood as blaming you for
not looking at something obvious (like use -findit-). This is not the
case, I was trying to give the answer and give an extra tip at the same
time. These -egen- functions are full of neat tricks, so if you want to
do something that is close to what is already implemented in an -egen-
function, than looking at that function might yield some useful tricks.
