OPNQRYF does not seem to be working

I have the following CL Program



             PGM        PARM(&CUST &MAST &LANG)

             DCL        VAR(&CUST) TYPE(*DEC) LEN(8 0)
             DCL        VAR(&MAST) TYPE(*DEC) LEN(8 0)
             DCL        VAR(&CUSTA) TYPE(*CHAR) LEN(8)
             DCL        VAR(&LANG) TYPE(*CHAR) LEN(3)
             DCL        VAR(&QRYSEL) TYPE(*CHAR) LEN(128)
             DCL        VAR(&ZERO) TYPE(*DEC) LEN(8 0) VALUE(0)

/*------------------------------------------------------------------*/

             CHGVAR     VAR(&CUSTA) VALUE(&CUST)

             CHGVAR     VAR(%SST(&QRYSEL 1 10)) VALUE('CPMAST *EQ')

             CHGVAR     VAR(%SST(&QRYSEL 12 8)) VALUE(&MAST)

             IF         COND(&CUST *NE &ZERO) THEN(DO)
             CHGVAR     VAR(&QRYSEL) VALUE(&QRYSEL *CAT 'CPCLOC *EQ +
                          ' *CAT &CUSTA)
             ENDDO

             OVRDBF      LABCMPL1 SHARE(*YES)

             OPNQRYF    FILE((LABCMPL1)) OPTION(*INP) +

             CHGVAR     VAR(%SST(&QRYSEL 1 10)) VALUE('SAMAST *EQ')
             CHGVAR     VAR(%SST(&QRYSEL 12 8)) VALUE(&MAST)


             IF         COND(&CUST *NE &ZERO) THEN(DO)
             CHGVAR     VAR(&QRYSEL) VALUE(&QRYSEL *CAT ' SACUST *EQ +

                          ' *CAT &CUSTA)
             ENDDO


             OVRDBF      LABMASL6 SHARE(*YES)
             OPNQRYF    FILE((LABMASL6)) OPTION(*INP) +

                          CRTFILE(*YES) */

/*------------------------------------------------------------------*/

/*------------------------------------------------------------------*/

             CALL       PGM(LBK0UPR) PARM(&CUST &MAST &LANG)


             DLTOVR     FILE(*ALL)

            CLOF       OPNID(LABCMPL1)
            CLOF       OPNID(LABMASL6)

            ENDPGM


It is selecting no records in the RPG IV program (LBK0UPR).

If the commented out CPYFRMQRYF statements are run the data is selected 
correctly in those files. Ihave tried using POSDBF

It does not help.



I have been through the archives and others are hinting at these problems. The 
access paths were already shared open and i have tried removing the OVRDBF  
commands none of it seems to make a diffrence. Am I going Mad. I have used 
OPNQRYF much in the past, but with RPG III or 400 whatever



Anyone solved this
