An error of variable type?

I've an error that I don't understand, it seems that that the problem is that my parameters into the shell are not of the same type as what they are in my SQL Database.

For a better understanding: I've a file doc.lst where i've three important things on each line seperated by spaces and i want to use this things as parameter for an UPDATE in my database. Every line will be readen, every part will be used as a parameter and will update my database.

I've a SQL query that is :

    UPDATE PE P
    SET P.DATED='&1', P.DATEF='&1', P.CODA='&3', P.CODB='&2'
    WHERE P.G_BAT=1;
    COMMIT;

And a shell that is :

    IFS=$'\n'
    for i in $(cat $LST_HOME/doc.lst)
    do 
    sqlplus64 $User/$Pass@$ORACLE_SID << EOF
    P1=$(echo $i | awk '{print $1}')
    P2=$(echo $i | awk '{print $2}')
    P3=$(echo $i | awk '{print $3}')
    @$SQL_HOME/update_p.sql $P1 $P2 $P3
    commit;
    exit
    /data/jdk1.6.0_XX/bin/java -cp fr.bla.bla.bla 
    EOF

I've got this error :

    SQL> SP2-0734: unknown command at the beggining of "P1=12/03/2..." - end of the line is ignored.
    SQL> SP2-0042: unknown command "P2=0" - end of the line is ignored..
    SQL> SP2-0042: unknown command "P3=FSL" - end of the line is ignored..

I don't really understand where and how i've to make modifications.
