Shell Programming and Scripting

Hello,
i am using '#!/bin/bash', i want to make a loop in pl/sql, this loop takes values from a table according to some conditions, each time the loop choose 3 different variables. What i am not able to do is that during the loop i want my shell script to read this 3 variables and run a shell script.
Here is a clarification:

My pl/sql is:
-----------------------------------------------------------------------
DECLARE
gn_bossid NUMBER(38);
gn_bossaccountid NUMBER(38);
gn_bossaddress NUMBER(38);
gn_voip_directoraddress NUMBER(38);
value1 NUMBER(38);
value2 NUMBER(38);
value3 NUMBER(38);

BEGIN

FOR voip_cparty IN (SELECT V.boss_id, V.bossaccount_id, V.bossaddress
INTO gn_bossid, gn_bossaccountid, gn_bossaddress
FROM Tbossesdata V
WHERE STATE IN ('A')
)
LOOP
BEGIN
value1 := gn_bossid;
value2 := gn_bossaccountid;
value3 := gn_bossaddress;

(1- here i want the shell to read this values
2- Call this same script to perform some other actions according to this values)

END;
END LOOP;
END;
---------------------------------------------------------------------------------------------------

I want the values value1, value2, and value3 to be readen by a shell script inside the loop where the loop is searching and calling the script to run.

what commands should be written in pl/sql and shell to perform this?

I appreciate your kind help.
Thanks!

There is no simple way to do it (unless you want to try some SQLJ procedures etc. which may be able to call an external program - I havn't explored that).
