I'm looking for some examples of extracting data from grib files using

The Grib1Dump utility shows the output at the bottom of this message.
However, when I
load the file using the code below, I get zero records. I'm new to
grib files, and my understanding
is that there should be a record for each parameter.

Hiya,

GribDump is just to dump the headers of the Grib files, most Grib data is large 
so we use the index approach and a utility GribGetData ie

Grib(1|2)Indexer to index the records in the Grib file


# Grib(1|2)GetData to extract the data on a parameter basis.
# Parameter and level lookup routines. See Parameters
