Hey Owen,

>You da MAN!!!     ;o)

Why, thank you :-)

>I really appreciate you taking the time to debug the code.

No worries.

>All the best,

I tested out the creation of an ABV field from the 0 Z AVN run on
adde.ucar.edu with success:

DATALOC ADD RTGRIDS ADDE.UCAR.EDU
LWU DEL GRID0001
GRDCOPY RTGRIDS/AVN MYDATA/GRIDS.1 DERIVE=ABV LEV=300 DAY=178 TIME=0 FHOUR=6 
GPRO=MERC SUBSECT=0 90
Total grids copied=1

GRDCOPY - done

I then listed the results using GRDLIST, and see a ramification of the
change I made:

GRDLIST MYDATA/GRIDS.1 NUM=ALL FORM=ALL
Dataset position 1      Directory Title=
PAR    LEVEL       DAY        TIME    SRC FHOUR     FDAY       FTIME  GRID  PRO
---- --------- ------------ -------- ---- ----- ------------ -------- ----- ----
ABV   300 MB   27 JUN 03178 00:00:00  AVN     6 27 JUN 03178 06:00:00     1 MERC
Total pts= 21097 Num rows=  73  Num columns= 289    received:  2003178 040911Z
GRIB ID numbers: Geographic =***; PAR = 33; Model ID = 96; Level type =100
Units of gridded variable are 1/S  Scale of variable is:   9
Mercator Projection
Min Lat=   0.00  Max Lat=  90.00  Min Lon=-180.00  Max Lon= 180.00
Latitude Increment= 1.2500  Longitude Increment= 1.2500
Number of grids listed = 1
GRDLIST - done

Notice that the value for the 'Geographic =' is '***'.  This is a
result of the geo ID now being 3744 and the format width specifier for
the GRDLIST output being an I3.  From my point of view, this is an
annoyance only, and it is one that will go away as soon as you upgrade
to Unidata McIDAS v2003 (as soon as I can make it available, like mid
July).

One last thought: the problem you originally wrote in about appears to have
been fixed by the same mod I made on adde.ucar.edu:

GRDCOPY RTGRIDS/AVN MYDATA/GRIDS.1 G1='PARAM T;LEV 400;DAY 178;TIME 0;FHOUR 
6;GPRO MERC' G2='PARAM T; LEV 300' MATH='G1+G2' NEWPAR=SUMT K 300 mb
Total grids copied=1

GRDCOPY - done

Hey, killing two birds with one stone aint half bad ;-)
