Thanks for the plug, but, again, this won't
work, for two separate reasons, one of which
applies to Daniel's suggestion:
1. Within a loop, you can repeatedly -replace-
the same variable in one or more
observations.
You can not repeatedly -generate- the same
variable (without -drop-ping it in the
interim, that is), any more than you can
do this in general.
Therefore, the device often used is to
-generate- a variable containing initial
values _before_ the loop and then
-replace- _within_ the loop.
2. More specifically, -vallist- gives
an ordered list of the distinct values
in a variable. For this to be what Jackie
wants, her m variable would have to
be monotonicly increasing. That's true of
her example, but I don't know that it is
true in general.
