Pointer not set for location referenced

        I'm having a problem that is driving me nuts.
        I have two RPGLE programs; one calls the other with parms.
        I've added a 7 character *ENTRY parm to the called program and
defined the parm in both programs in the D specs.
        The call looks like this (@RelsNo is the new parm):
        C                   CALL      'KBRLSR1 '              
        C                   PARM                    KPITEM    
        C                   PARM                    KPHOUSE   
        C                   PARM                    OQUANTY   
        C                   PARM                    @Origcode 
        C                   PARM                    KPCTRL    
        C                   PARM                    KPVNDR    
        C                   PARM                    @Ordnbr   
        C                   PARM                    @RelsNo   
        They compile fine. But when I run the programs, I get error: MCH3601
"Pointer not set for location referenced"
        I dug around through the archives and found message thread msg00680
which is the exact same problem. I tried all the suggestions but none of
them resolve my problem.
        Any ideas?
