All,

This person sent this personally to me, asking me to fix whatever might
be wrong with their FORTRAN code or their use of GrADS, such that displaying
the data variable results in the "constant field" message.  I feel that such
a request asks too much, especially of a single individual.  However, I
decided to repost it here, in case anyone here was feeling more generous.
I hope all of you can parse the convoluted attachment hierarchy.  %}

-Hoop

dear sir, =0Ai am using a topography and bathymetry program to extarct topg=
raphy and bathymetry data for 60e-100e,60s-equator, but when i am plotting =
it using grads it shows error given below. i am extarcting 1/12 degree bath=
