[GEMPAK #KJI-373009]: ENS_PROB limitation

David,

Here is an example:

NCEP produces 20 perturbation members (eg ftpprd.ncep.noaa.gov under
pub/data/nccf/com/gens/prod/gefs.20070605/06/pgrb2a) which I have
decoded such as f024 members:

gep01_2007060506f024.gem
gep02_2007060506f024.gem
gep03_2007060506f024.gem
gep04_2007060506f024.gem
gep05_2007060506f024.gem
gep06_2007060506f024.gem
gep07_2007060506f024.gem
gep08_2007060506f024.gem
gep09_2007060506f024.gem
gep10_2007060506f024.gem
gep11_2007060506f024.gem
gep12_2007060506f024.gem
gep13_2007060506f024.gem
gep14_2007060506f024.gem
gep15_2007060506f024.gem
gep16_2007060506f024.gem
gep17_2007060506f024.gem
gep18_2007060506f024.gem
gep19_2007060506f024.gem
gep20_2007060506f024.gem


The $GEMTBL/config/datatype.tbl has a template for GEFS that
provides a file name pattern:
gep*_YYYYMMDDHHfFFF.gem

To plot an ensemble function, I use GDFILE = {GEFS}

The wildcard "*" in the template will enable the {} to find multiple files.
