Hmm. You are using -rndbin-, a user-written program by Joe Hilbe and
Walter Linde-Zwirble, which is for Stata 3.1.
As documented at the help for -version- the random number
generator changed in Stata after version 3.1.
Therefore, there is no connection between
-set seed- in an interactive session under Stata 7,
and what happens when you run -rndbin-, because
different generators are concerned, the new and
the old (under -version-).
I think you need to edit a copy of -rndbin- and
-set seed- within that.
