I assume this question as:
") I have 2 programs  A and B. Now program A references Program  B and Program B references Program A. How do you compile such inter-dependent objects in PL/SQL"

ANS:We can compile mutually referencing programmes using FORWARD declaration(specifying the declaration of one program in beginning of package body) inside a PACKAGE.
Example:
CREATE OR REPLACE PACKAGE test_pack
IS
gvar NUMBER:=0;
--PROCEDURE p1; --we can also achieve like this
END;
/

CREATE OR REPLACE PACKAGE BODY test_pack
IS
PROCEDURE p1; --forward declaration

PROCEDURE p2 
IS
BEGIN
P1;
END;

PROCEDURE p1
IS
BEGIN
p2;
END;

END;
