20010702: Trouble with gdinfo

Bob,

The message you are getting is that there are no 500mb TMPC 
grids matching at the last forecast time in the file, which
is true since the grid that would exist is TMPK.

If you want to see all the grids in the file, type at the gdinfo prompt"
"restore defaults/gdinfo" 
or 
gdattim = all
glevel = all
gvcord = all
gfunc = all  

If you just want to see the 500mb TMPK grids at all forecast times
for example:
 GDFILE   = eta
 LSTALL   = yes
 OUTPUT   = t
 GDATTIM  = all
 GLEVEL   = 500
 GVCORD   = pres
 GFUNC    = tmpk
