[GEMPAK #NZW-716390]: [Fwd: GEMPAK problem with gdprof]



Greg,

You didn't send the question to support while I was on vacation, so it
wasn't in the support queue on my return.

The only parameters that make sense for a skewt are tmpc and dwpc,
but your function sub(tmpc,dpdk) won't have a name DWPC by
default (ie, it will have a name subtmpcdpdk), so its not
a valid skewt parameter. You need to assign the grid
the name DWPC in your GFUNC as:

GFUNC    = sub(tmpc,dpdk)//dwpc
