[ncl-talk] Making new variables in a loop

[Dave Allured - NOAA Affiliate]

Barry, no, you can not create new memory variables in a loop.  You CAN
create new file variables in a loop.  But I sincerely doubt that is what
you want to do.

I recommend using the reassignment operator ":=".  If that gives you a
different error, then debug that specifically.  If that is still a problem,
please show us what you mean by "another error".  HTH.
