Ioana (and list) --
The thing is, when you use "exec" it spawns a subshell, and so invoking "env"
or "setenv" will only set variables within that subshell; in other words,
once that exec command finishes, those variables are gone.
I think the simpler way to do what you want would be something like this:
set DIR [exec sh -c {date +%m_%d_%H_%M_%y}]
exec mkdir $DIR
I haven't tested this, but hopefully it will be helpful...
