[GEMPAK #IUV-151200]: gempak question

Hi Frank,

So far I've been unable to come up with a solution for this.  GDLIST is 
designed to output values for every grid point contained within GAREA, so 
there's no direct way around having the average value reported for each grid 
point.  If you're scripting and would like to use the average value after it's 
calculated by GDLIST, one kludgy solution would be to save the output to a text 
file and then parse that file with a short python or perl script.  As I said, 
kludgy, but right now I can't offer you an easy and direct fix.

Best,

Michael James
