Very good.

McIDAS understands the MCPATH environment variable.  I added MCDATA
as a Unidata construct, and then set MCPATHs such that the first
directory included in MCPATH is MCDATA.  If your script is not
doing the same thing, the reason for ABITRUCOL.MCB not working
as expected/hoped would be explained.

Here is how I set MCPATH in the scripts that I run as 'ldm' to
generate LOTS of content for the IDD UNIWISC feed:

# LDM HOME directory
LDMHOME=`echo ~ldm`

# Define McIDAS environment based on LDMHOME
MCHOME=`echo ~mcidas`
MCDATA=$LDMHOME/mcidas/data
MCPATH=${MCDATA}:$MCHOME/workdata:$MCHOME/data:$MCHOME/help
PATH=$LDMHOME/mcidas/bin:$PATH:$MCHOME/bin:$LDMHOME/bin:$LDMHOME/util:$LDMHOME/decoders

if [ -f "${MCDATA}/MCTABLE.TXT" ]; then
  MCTABLE_READ="${MCDATA}/MCTABLE.TXT;$MCHOME/data/ADDESITE.TXT"
else
  MCTABLE_READ="$MCHOME/data/ADDESITE.TXT"
fi
export MCHOME MCDATA MCPATH MCTABLE_READ PATH

#log_message "INFO: MCDATA = $MCDATA"

# Everything happens in the MCDATA directory
cd $MCDATA

As you can see, I define and then CD to the $MCDATA directory AND make
sure that it is the first directory in the MCPATH definition.  SSEC's
ABITRUCOL.MCB script assumes it is run inside an environment in which
MCPATH is fully defined.  The various McIDAS commands run (IMGCOPY,
IMGREMAP, IMGOPER) will read and write to the first directory in
MCPATH that it can read from for reads and write to for writes.

OK, I'm around all day.  Please send me a Meet invitation when you have
time, and I will join you.
