 # process
 x="JAN=01 FEB=02 MAR=03 APR=04 MAY=05 JUN=06 JUL=07 AUG=08 SEP=09 OCT=10 NOV=11 DEC=12"
 for i in $(echo "$x" | sed 's/=[0-9]*//g') ; do
  y=$(sed "s/.*\($i\).*/\1/" $infile); y1=$(echo "$x"| sed "s/.*$i=\([0-9]*\).*/\1/")
  sed -i "s/\(.*\)|\(.*\)$y\(.*\)|\(.*\)/\1|$y1\\\\\2\\\\\3\4|/g" $infile 2>/dev/null
 done ;  more $infile
done
