20030904: GDDIAG Error

Patrick,

I ran a test on some grids that I had and it seems to work for 
me like:

 GDFILE   = test1.gem
 GDOUTF   = test1.gem
 GFUNC    = mul(avep24m,cntp24m)
 GDATTIM  = 030905/0000F024:030905/0600F024
 GLEVEL   = 0
 GVCORD   = none
 GRDNAM   = augp
 GPACK    =  
 GEMPAK-GDDIAG>r


    TIME1             TIME2         LEVL1 LEVL2   VCORD PARM
030905/0000F024    030905/0600F024      0          NONE AUGP        
Enter a new grid parameter name, <cr> to accept or type EXIT:
 Parameters requested: GDFILE,GDOUTF,GFUNC,GDATTIM,GLEVEL,GVCORD,GRDNAM,
 GPACK.
 GEMPAK-GDDIAG>

If you want to GDMOD the 2 grids in question to a file
and just send me that, I can check your grids here.

Also let me know the OS and version you are using.

It almost sounds like one of your grids is empty or corrupt. Have you 
verified that you didn't hit the max number of grids in your file
along the way, etc? Of couse, if you can see them independently
with gdlist etc, then that isn't the problem.
