You should also remove the MCH3601 message from the joblog.  There is no point 
in
cluttering the joblog with unnecessary messages.  That is the difference 
between a
good programmer and a merely competent one.  You should be coding:

              CHGVAR     VAR(&IPNAME) VALUE(&RIPNAME)
              MONMSG     MSGID(MCH3601) EXEC(DO)
                RCVMSG     MSGTYPE(*EXCP)
              ENDDO
or
              MONMSG     MSGID(MCH3601) EXEC(RCVMSG MSGTYPE(*EXCP))

The same thing is true for all instances where messages are monitored and 
handled
in the program.  A classic example is CHKOBJ followed by MONMSG and then a 
CRTxxx
command.  Clean up the joblog.  A certain automated operations software house
should practice this technique.

Also, since the real work is done in the RPG program and the sole purpose of the
CLP is to call the RPG and handle the parameters you could use the RPG program 
as
the Command Processing Program directly.  Use the %ADDR built-in function to 
test
the parameter before assigning a value to it.  Of course that means the 
parameter
names must be different from the database names but that is a GOOD THING.  For
example:

       /TITLE 'Retrieve OrderWriter Control Record

       /COPY QRPGSRC,HDefault

      FACCSCNT   IF   E             DISK    UsrOpn

      D @No             C                   'N'
      D @Yes            C                   'Y'
      D P_IPNAME        S                   LIKE(IPNAME)
        etc, etc, etc.
      D P_OWCtlFnd      S              1

          if (%ADDR(P_IPNAME) <> *NULL);
            P_IPNAME = IPNAME;
          endif;

        etc, etc, etc.

         if  (%ADDR(P_OWCtlFnd) <> *NULL);

        etc, etc, etc.

         if  (%ADDR(P_OWCtlFnd) <> *NULL);
           P_OWCtlFnd = @No;   // or *BLANK
