Re: one question: why doesn't work when run for 2nd time?

Hi Gaorz,

Here's a quick guess:

When you run your script for a second time the region has been
restricted by the command
    set region/x=99.375e:123.75e/y=0.952s:23.809n
This can effect the evaluation of "lats" in
    define axis/y/from_data/name=ygrd/unit=degrees lats

Try "CANCEL REGION" before re-running the script.

P.S. A nicer syntax is available for the latter command as of
Ferret V5:
    define axis/y/unit=degrees ygrd = lats
