RE: 20030401: A curious [NGD 0] error in NMAP2

Thanks Steve..

I guess we downloaded the binary version because I did se the source code in
the path you pointed out.

So if I understand correctly, we would have to get the source code version
(if that is possible) and then make the change ourselves on the line you
pointed out in your response?

Or maybe future binary versions of NMAP2 may come without this Error
message.

Thanks again

Lewis

Lewis, 
The value of the error return of "0" being printed out means that
the plot succeeded. You should only need to worry about these if 
the status is non-zero.

I see where the logging exists in
$GEMPAK/source/programs/gui/nmap2/nmap_dsp.c
(line 1171), ane the call to er_wmsg should likely check first 

if (ier != 0)
        er_wmsg...

That would avoid unnecessary truning the error button RED.
