20001207: Gempak5.6 color tables

Mike,
The GEMCOLTBL environmental variable was something I provided in GEMPAK 5.4
in $GEMPAKHOME/source/driver/active/gn/csctbl.c to override the
default color table (now coltbl.xwp when ntl isn't running).
I haven't added that feature into GEMPAK 5.6 since it won't work with all
the device drivers.
Instead, you can set the colors using the gempak program gpcolor.
You can either set the colors explicitly, or use a short nawk script
such as the following to set the colors from your coltbl.precip table.
This scripts can either be within your script, or made into an
external script for calling from lots of scripts.
#!/bin/csh -f
# this csh script fragment can be used to create an input file for gpcolor
# from a coltbl file.
set FILE="$GEMTBL/colors/coltbl.precip"
set DEVICE=xw
nawk -v COUNT=0 -v LINE=0 -v GDEV=${DEVICE}\
'index($0,"\!") != 1 { \
if(COUNT == 0) printf "DEVICE = %s\n",GDEV \
if(LINE == 0) { printf "COLORS = "} else { printf ";"} \
printf "%d=%d:%d:%d",COUNT,$3,$4,$5 \
if(LINE == 5) { \
printf "\n r \n \n" \
LINE = 0 \
} \
else LINE = LINE + 1 \
COUNT = COUNT + 1 \
} ' $FILE >! /tmp/setcols.$$
cat >> /tmp/setcols.$$ << EOF
r
e
EOF
gpcolor < /tmp/setcols.$$
rm /tmp/setcols.$$
exit 0

Let me know if you still have trouble.
