call multiple procedures in 1 procedure

Hi,

Please help me out with the following. I have created 3 procedures and I would like to put these in 1 procedure and call them at the same time. 2 of these procedures have more than 1 input parameters. How can I write this?

I have already tried to:

CALL 'PROCEDURE1' ();

CALL 'PROCEDURE2' (:IP1,:IP2,:OUT);

CALL 'PROCEDURE3' (:IP1,:IP2,:IP3,:IP4,:IP5, :OUT);

but i get "expression cannot be used as an assignment target: :IP1"

please help me out. thnx!
