Here's a follow-up replacement to the patch I sent earlier, this adjusts some of the semantics of the dynamic variable setting. Namely, dynamic vars can hook a set handler (which RANDOM uses to adjust the seed). They'll only lose their dynamic status if they're unset. I've used the same approach that bash does to come up with the random number, mostly just for consistency. For example: $ echo $RANDOM 13759 $ echo $RANDOM 20057 $ echo $RANDOM 1502 $ export RANDOM=42 $ echo $RANDOM 24179 $ echo $RANDOM 2046 $ unset RANDOM $ echo $RANDOM $ export RANDOM=42 $ echo $RANDOM 42 $
