This apparently has something to with the fact that -rndbin- is
a Stata version 3.1 program. If you change the version # within
-rndbin- to 5 then the -set seed #- is honored (and the program
seems to still work correctly).
Someone from StataCorp will need to explain why this behaves the
way it does under version 3.1; my memory is not good enough to
know how -set seed- and random numbers worked back then!
