[Fwd: another grads question]

[Sim Aberson]

I am having another frustrating GrADS issue with GrADS2 on my mac.  I am trying
to make more station plots.  I have code to write out the station plot data.  I
have done this before with no problem, but get an error now.  I am attaching a
binary version of that file (fort.10) and a control file (fort.13).  When I run
that through stnmap, I get an error:

stnmap -v -i fort.13
    Name of binary data set: fort.10
    Number of times in the data set: 1
    Number of surface variables: 0
    Number of level dependent variables: 5

Starting scan of station data binary file.
Binary data file open: fort.10

Processing time step 1
    Invalid station hdr found in station binary file
    Possible causes:  Invalid level count in hdr
                      Descriptor file mismatch
                      File not station data
                      Invalid relative time
                      Invalid sequential format
      levs = 0  flag = 27  time = 1.4013e-45

The contents of the file fort.13, in ascii, are:

   XXXXXX1   18.91675      -51.42435       0.000000               1           0

     3000.000       10.93500       80.70000      -25.08000       15.18000
   XXXXXX7   18.89175      -51.36465       0.000000               1           0
     3500.000       8.165000       68.85000      -23.95500       16.06000
   XXXXXX7   18.89175      -51.36465       0.000000               0           0


So, according to the first line, levs should be 1, flag should be zero, and time
should be zero.  But the above from stnmap has very different values.  Am I
missing something very fundamental from the documentation?  I'm stumped.

Thanks,
Sim
