echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version bash sed

echo

FILE=${1-data1}
echo " Input file $FILE:"
cat $FILE

echo
echo " Results from sed:"
sed '/WISH_LIST="/,/^"$/{
/WISH_LIST="/b
/^"$/b
d
}' $FILE

exit 0

GNU bash 2.05b.0
GNU sed version 4.1.2

 Input file data1:
