Kevin and all...

I added the PD# 2 and 12 entries (eg Derived forecast based on all ensemble 
members at a point in time, and Derived forecast based on all ensemble members 
for a time interval) for the gavg and gspr files as well and updated the tables 
posted.

Also, for the 5.9.4 distribution, I have added a %ens% file name template to 
the dcgrib2 decoder so that the individual members, average, spread etc can be 
written to individual files using a single filename pattern.  The GEMPAK 
ens_xxx() functions will enable you to compute derived and probabalistic 
quantities based on the individual members using the GDFILE={file(s)} syntax. I 
am adding information to the tutorial and examples pages to illustrate these 
capabilities.

Thanks again Steve. I can now decode the control and perturbation fields. However, it looks like the tables need to be further expanded so they can decode the "geavg" and "gespr" bulletins.

Regards,

Kevin
