RE: Gempak error [GEMPLT 1] NCTRLP - Broke out of contour loop.

when setting subbox factor to an arbitrarily high level under the contur parm

I'm using a subbox of 2 and it normally works just fine (it being the
script generator I've written). In the past 2 days running this on all
hours of the GFS, GEFS, and NAM this error has occurred twice:

For hour 78 of the 30/18Z GFS
For hour 210 of the 31/12Z GEFS

And there is an older system which my new generator is based off of that
seems to run just fine on those hours providing the same (I believe, it
doesn't leave the script it generated for debugging) parameters to
gdplot2_gf.

Here is the generated script for hour 210 of the GEFS. I think in my
inexperience I'm missing something subtle.

Thanks,
Edgar Bering
