Answer 1

Your program's signature has three syntax errors.

1. It does not return a value therefore it is a PROCEDURE not a FUNCTION
2. You have specified the length of the third argument; that is not valid for PL/SQL parameters.
3. The DECLARE keyword is only used for anonymous blocks. It is not valid syntax for named PL/SQL units (the IS or AS keyword fulfils its function of marking the variable declaration section).

So your code should start like this

CREATE OR REPLACE procedure MOBLIE_RX_VERIFICATION
   (ARG_DAD_ID IN   NUMBER,
    ARG_PATIENT_NAME IN VARCHAR2,
    ARG_VERIFY_MODE VARCHAR2)  
AS  
    NEW_CCH_ID NUMBER;

Answer 2

1. replace "AS" to "IS"
2. add "return number" or change function to procedure
