Getting return value from sqlplus script while running a unix job

Question

I am trying to run a unix script that calls sqlplus. The following code outlines the unix/sql code that I trying to execute:
return_count=`sqlplus $ORACLE_ID/$ORACLE_PWD@$ORACLE_SID <<EOF | grep '^RETURN_VAL' | sed 's/^RETURN_VAL//'
SET SERVEROUTPUT ON
VARIABLE ReturnValue NUMBER
EXEC :ReturnValue := 1
BEGIN
UPDATE seq_control_nbr
SET table_seq_nbr = table_seq_nbr + 1,
last_updt_dttmstp = systimestamp,
last_updt_user_id = 'ECVMSONS'
WHERE table_key = 'ONSTAR';
IF SQL%ROWCOUNT = 1 THEN
COMMIT;
:ReturnValue := 0;
ELSE
ROLLBACK;
:ReturnValue := 99;
END IF;
DBMS_OUTPUT.PUT_LINE ('RETURN_VAL '||:ReturnValue);
END;
EXIT
EOF`
The above outlined sqlplus script does run because the values on the table are updated. However, I cannot get the value of ReturnValue to be displayed, so it can be returned to the unix script.
Any ideas?

ok do the following:-
return_count=`sqlplus $ORACLE_ID/$ORACLE_PWD@$ORACLE_SID <<EOF
SET SERVEROUTPUT ON
whenever OSERROR exit 1
whenever SQLERROR exit 2
UPDATE seq_control_nbr
SET table_seq_nbr = table_seq_nbr + 1,
last_updt_dttmstp = systimestamp,
last_updt_user_id = 'ECVMSONS'
WHERE table_key = 'ONSTAR';
EXIT
EOF`
rowsupdated=`echo $return_count|cut -f1 -d' '`
echo "Rows updated =" $rowsupdated
retcode=`echo $?`
case "$retcode" in
0) echo "Update executed successfully on " ;;
1) echo "Update failed OSERROR ";;
2) echo "Update failed SQLError " ;;
*) echo "Update failed - Unknown Error ";;
