NAM grib2 error

[Oliver König]

Hello Grads users,
 I have grads v2.0.a1 and grib2 v1.6.1. Processing GFS model grib2 files works
fine. I tried to process NAM (North American Mesocale grib2 model data from
NCEP, 12 Km Lambert Conformal).

This is the error I get when creating the control file for the NAM grib2 file:

$ wget

$ g2ctl.pl -verf nam.t00z.awip1212.tm00.grib2 > nam2.ctl
