Dan,

The NCEP file structure that the ENS_name functions are based on assumes that 
they have "N" separate files
each with the TMPK parameter (eg using PDSEXT=NO in NAGRIB). The error message 
you have is that TMPK isn't 
found...which it isn't because the parameter with the ensemble extension aren't 
what is being looked for.

The NCEP ENS template is:
ENS          $MODEL/ens                ens_YYYYMMDDHH_*

where the above "*" matches separate files ens_YYYYMMDDHH_P000, 
ens_YYYYMMDDHH_P001, etc
and the function ENS_SAVS(TMPK) will look for TMPK in the GDFILE={ENS}.
