Passing Pl/Sql variables into shell variables.

Question

I have written a file that ftp information from one pc to another in unix.
All you have to do is supply a user_name/password and machine name to which ftp program will connect to.
All connection information like user_id,password, machine name are stored in an oracle table FTP_TBL.
It has the following fields:
FTP_TBL
================
USER_ID      NOT NULL VARCHAR2(100);
USR_PASSWD      NOT NULL VARCHAR2(50);
TO_MACHINE     NOT NULL VARCHAR2(50);
I have called a pl/sql script in unix shell.
This script selects all the connection information from FTP_TBL and populates the pl/sql variables with the
information.
Now i want the pl/sql variables like V_TO_MACHINE,V_USR_ID,V_USR_PASSWD to be passed on to unix variables
To_MACHINE, USR_ID AND USR_PASSWD.
How can i do this?
============================================================================================================
sqlplus -s <<+++ >> $LOG_FILE
$USER/$PASSWD
set serverout on SIZE 1000000
DECLARE
V_TO_MACHINE VARCHAR2(100);
V_USR_ID VARCHAR2(50);
V_USR_PASSWD VARCHAR2(50);
BEGIN
     BEGIN
          SELECT TO_MACHINE, USER_ID, USR_PASSWD
          INTO V_TO_MACHINE,V_USR_ID,V_USR_PASSWD
          FROM FTP_TBL;
     EXCEPTION
          when others then
          dbms_output.put_line('ERROR|SQLPLUS|'||ERROR||'|'||sqlcode||'|Failed during selecting configuration information.'||sqlerrm );
     END;
END;

#======================== VARIABLES =====================
TO_MACHINE=$1
USR_ID=$2
USR_PASSWD=$3
#========================== MAIN ========================
ftp -vnd $TO_MACHINE << ++ 1>>$STA_LOG_FILE 2>&1
user $USR_ID $USR_PASSWD
prompt off
get $OR_DATA_DIR/ASC.STADATA $HOME_DIR/ASC.STADATA
bye
++
# testing the exit status of FTP
egrep "Transfer complete" $STA_LOG_FILE >/dev/null
if [ $? = 0 ]
then
echo >> $STA_LOG_FILE
echo "FTP Successfully Done" >> $STA_LOG_FILE
else
echo >> $STA_LOG_FILE
echo "FTP UnSuccessfull" >> $STA_LOG_FILE
exit 1
fi

Here an example of how to pass variables to the shell script :
TEST@db102 SQL> select ename, job, dname from emp,dept
  2  where empno = 7902
  3  and emp.deptno = dept.deptno;
ENAME      JOB       DNAME
FORD       ANALYST   RESEARCH
TEST@db102 SQL> exit

With the Partitioning, OLAP and Data Mining options
[ora102 work db102]$ cat disp_var.sh
set `sqlplus -s test/test << EOF
set pages 0
select ename, job, dname from emp,dept
where empno = 7902
and emp.deptno = dept.deptno;
exit
EOF`
echo $1 $2 $3
