Hi,
I am trying to eliminate duplicate records from a file of Lrecl = 4500.
I am trying to use the following
Code:
SORT FIELDS=(1,4500,CH,A)
SUM FIELDS=NONE


Its giving me the following error
Code:
            SORT FIELDS=(1,4500,CH,A)                     
                                   $                     
ICE017A C CONTROL FIELD DISPLACEMENT OR LENGTH VALUE ERROR
            SUM FIELDS=NONE                               


I see it might be that the length specified is not acceptable. Is there anyway in which I can perform the sort on the whole file and eliminate the duplicate records.

Thanks,

Muffirulz,

The following DFSORT/ICETOOL jcl will give you the desired results.

Code:

//STEP0100 EXEC PGM=ICETOOL 
//TOOLMSG  DD SYSOUT=*       
//DFSMSG   DD SYSOUT=*       
//IN       DD DSN=Your 4500 lrecl dataset,

//T2       DD DSN=&&T2,DISP=(,PASS),SPACE=(CYL,(X,Y),RLSE)     
//KEEP     DD DSN=YOUR FINAL OUTPUT WITHOUT DUPS,
//            DISP=(MOD,CATLG,DELETE)

       OVERLAY=(4501:SEQNUM,8,ZD)),
        IFTHEN=(WHEN=NONE,
       OVERLAY=(4501:8X))
/*
//CTL3CNTL DD *
  OUTFIL FNAMES=KEEP,OUTREC=(01,4500)
/*


Hope this helps...

Cheers

achittu,

If you had followed your own advice and tried that, you would have found out that it doesn't work. 4500 bytes is larger than the limit allowed for that kind of thing.
