Reply with quote

The requirement is -
The input file has one header. I need to sort only detail records excluding header record. I have tried SKIPREC which is discarding header record altogether. But I need that header record to appear in the output. Is there any other way?
Thanks in advance

Thanks and Regards,
Debasish.

Hi There,

U can use following DFSORT statements:

Code:
//SYSIN DD *
** Put special key of '1' in 81 for data records.
     INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:C'1')),
** For header record, put special key of '0' in 81.
               IFTHEN=(WHEN=(1,4,CH,EQ,C'HEDR'),
                  OVERLAY=(81:C'0')),
** Sort by special key ('0', '1') and then regular key.
    SORT FIELDS=(81,1,CH,A,14,10,CH,A)
** Remove special key.
    OUTREC BUILD=(1,80)
/*


Here I assume that ur header record contain HEDR at first 4 bytes & key is at 14 the position & offset is of 10 bytes
