Differences between GRPHGD in 5.6.d.1 and 5.7.2

Steve,

Thanks for the e-mail about the dcreanal program.  As it turns out, I have 
managed to get my data in the GRIB format, so I don't have to worry about 
converting it to NetCDF.

I did have another question for you.  I did finally use NMAP and the GRPHGD 
program to convert hand analyses to gridded data that I could later plot, which 
I had sent you an e-mail about several weeks ago.  Recently, some of the 
computers in our lab have been upgraded to the newest version of GEMPAK, 5.7.2, 
while the other computers still run GEMPAK 5.6.d.1.  I have tried to create 
some grids on 5.7.2 boxes with VGF files that I created using 5.6.d.1.  When I 
try to use GRPHGD in NMAP on a 5.7.2 box, I get an error message that says:

"Grid data for contouring is all missing or constant."

These VGF files still work to create grids on 5.6.d.1.  Any idea as to what the 
problem may be?  For now I've just continued to use the 5.6 program to create 
my grids, but once those get replaced, I need to know how to use 5.7! Thanks 
again for all your help.

Tom
