Calling stored procedure from unix shell script

Question

Hello,
I am facing a problem while calling a stored procedure from UNIX shell script. I want to return a output variable from the stored procedure to the UNIX environment.
Here is the code-
#!/bin/sh
OUTPUT=`sqlplus cmag/magnum@dw <<ENDOFSQL
set serveroutput on;
var prd_out varchar2(100);
exec create_pm_window(:prd_out);
exit;
ENDOFSQL`
echo " output is - $OUTPUT"
The problem is :prd_out is not getting copied to shell variable OUTPUT.
I have a dbms_output.put_line in the stored proc create_pm_window and I can see that prd_out is getting populated.
Any help is really appreciated.
Thanks'

First step :
make sure the PL/SQL works as expected.
Does the following display the expected output executed from SQL*Plus ?
set serverout on
declare
prd_out varchar2(100);
begin
create_pm_window(prd_out);
dbms_output.put_line('output is '||prd_out);
end;
I don't have your procedure, but using a dummy procedure like :
Scott@my10g SQL>create procedure foo(p_out in out varchar2)   
  2  is
  3  begin
  4  select 'Hello '||instance_name into p_out from v$instance;
  5  end;
  6  /
Procedure created. and a toto.sh script as :OUTPUT=`sqlplus -s scott/tiger <<EOF
set pages 0 lines 120 trimout on trimspool on tab off echo off verify off feed off serverout on
var mavar varchar2(100);
exec foo(:mavar);
print mavar;
exit;
EOF`
echo "OUT = ${OUTPUT}"
exitIt works fine :[oracle@Nicosa-oel ~]$ ./toto.sh
OUT = Hello my10g
