Besides writing COBOL program, is it possible to use SORT on a job to validate trailer count on a file and return condition codes depending upon if number of detail records matching trailer count or not.

EXAMPLE 1
INPUT FILE:

Code:
1HDR
2DTLAAAAA
2DTLBBBBB
2DTLCCCCC
9TRL  00000003


Number of 2DTL records = 3, count on 9TRL record = 3
==> counts match and return code = 0

EXAMPLE 2
INPUT FILE:

Code:
1HDR
2DTLAAAAA
2DTLBBBBB
2DTLCCCCC
9TRL  00000004



Number of 2DTL records = 3, count on 9TRL record = 4
==> counts mismatch and return code > 0

You can use a DFSORT job like the following to do what you asked for. Note that you need z/OS DFSORT V1R5 to use NULLOUT (it's not supported in DFSORT R14).

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
1HDR
2DTLAAAAA
2DTLBBBBB
2DTLCCCCC
9TRL  00000004
/*
//SYM DD DSN=&&S1,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//TRL DD DSN=&&T1,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//SYSIN    DD    *
  OPTION COPY
  OUTFIL FNAMES=SYM,INCLUDE=(1,1,CH,EQ,C'9'),
    BUILD=(C'OCOUNT,+',7,8,80:X)
  OUTFIL FNAMES=TRL,REMOVECC,NODETAIL,
    INCLUDE=(1,1,CH,EQ,C'2'),
    BUILD=(8X),
    TRAILER1=(COUNT=(M11,LENGTH=8))
/*
//S2    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SYMNAMES DD DSN=&&S1,DISP=(OLD,PASS)
//SORTIN DD DSN=&&T1,DISP=(OLD,PASS)
//SORTOUT DD DUMMY
//SYSIN    DD    *
  OPTION COPY,NULLOUT=RC4
  INCLUDE COND=(1,8,ZD,EQ,OCOUNT)
/*

WallaceC,

Try this one pass DFSORT solution which will give you the desired results

Code:

//STEP0100 EXEC PGM=ICEMAN                           
//SYSOUT   DD SYSOUT=*                               
//SORTIN   DD *                                       
1HDR                                                 
2DTLAAAAA                                             
2DTLBBBBB                                             
2DTLCCCCC                                             
9TRL  00000003                                       
//SORTOUT  DD SYSOUT=*                               
//SYSIN    DD *                                       
  SORT FIELDS=COPY                                   
  OUTREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),
         IFTHEN=(WHEN=(1,4,CH,EQ,C'9TRL'),           
        OVERLAY=(81:+2,SUB,81,8,ZD,M11,LENGTH=8))     
                                                     
  OUTFIL NULLOFL=RC4,
  INCLUDE=(1,4,CH,EQ,C'9TRL',AND,07,8,ZD,EQ,81,8,ZD)
/*

Hope this helps...

Cheers
