[GEMPAK #APZ-498322]: Resend of gempak question with script attached

Hi Bob,

I had to make a number of edits to your script to get it to work.  Some of 
these may be peculiarities of your scripting environment and WRF grids, but to 
me they look like input errors.

1) $RESPOND is a hidden variable in GEMPAK and is not listed in programs like 
GDPROF.  If you set \$RESPOND = no and run a script, it is saved as "no" even 
after exiting the program and calling GPEND.  running another GEMPAK program 
will use this definition.  Therefore, to unset $RESPOND = no you must enter 
\$RESPOND=yes at least once and run it.  I have confirmed that this will is the 
case with your script.  That's the big problem solved, but there are other 
smaller issues.

2) device  = gif | ${date}${cycle}-${fh}.gif | 6;10
This directs GPLT to create a gif image size 6x10 pixels.  I could not get GPLT 
to create this image likely because the dimensions are below some minimum.  I 
had to remove size definition (DEVICE = gif | filename.gif) but also checked 
that (DEVICE = gif | filename.gif | 600;1000 ) worked.

3) I had to change XAXIS to "-20/40/5" using a recent GFS run to confirm both 
TEMP and DEWP are plotted vertically, which they are.

I have attached my example script.  Let me know if you have more questions.
