20050207: ezset

Wenxian,

When a GEMPAK program starts, it lists out the previous settings
in gemglb.nts (eg what you had previously used), then
your redirection from "<< EOD" will occur, so you won't see those 
settings unless you use the "display" command such as:
gdinfo << EOD
   GDFILE = $MODEL/${model_lc}/${model_lc}_${ymdh}
   TEXT = 1.5/2//hw
   display
   run

   exit
EOD

The "display" command will sow the current settings after the parameters have
been set you the redirection, but it is not necessary for the
program to be run with the values that were set- though your script
snippet never runs the prigram velow.
