All,

I wrote a control card that looks like below,

Code:

SORT FIELDS=(27,4,ZD,A)                                                 
INCLUDE COND=(27,4,CH,GE,C'0300',AND,                                   
              27,4,CH,LE,C'0701')                                       
INREC FIELDS=(1,4,C' ',33,16,C' ',368,5,PD,TO=ZD,LENGTH=8,C' ',21,4)     
OUTFIL FNAMES=SORTOUT,VTOF,BUILD=(1,35)                                 


It returns me no records (but i was expecting some records).

So I have split the control cards in to two, and ran in two saparate JOBs

first one job has a control card

Code:


  SORT FIELDS=(27,4,ZD,A)                                                   
  INREC FIELDS=(1,4,C' ',33,16,C' ',368,5,PD,TO=ZD,LENGTH=8,C' ',21,4)     
  OUTFIL FNAMES=SORTOUT,VTOF,BUILD=(1,35)                                   



second one, with the following control card

Code:

  SORT FIELDS=COPY                             
  INCLUDE COND=(27,4,CH,GE,C'0300',AND,         
                27,4,CH,LE,C'0701')             


Now it has returned the data as i was expecting.

Can some one explain, why it is happening so. For me both looks same.

Found it,

Code:


  SORT FIELDS=(27,4,ZD,A)                                                 
  INREC FIELDS=(1,4,C' ',33,16,C' ',368,5,PD,TO=ZD,LENGTH=8,C' ',21,4)   
  OUTFIL FNAMES=SORTOUT,VTOF,BUILD=(1,35),                               
  INCLUDE=(27,4,CH,GE,C'0300',AND,                                       
           27,4,CH,LE,C'0701')                                           


did the trick.

But still can't understand what

Code:

SORT FIELDS=(27,4,ZD,A)                                                 
INCLUDE COND=(27,4,CH,GE,C'0300',AND,                                   
              27,4,CH,LE,C'0701')                                       
INREC FIELDS=(1,4,C' ',33,16,C' ',368,5,PD,TO=ZD,LENGTH=8,C' ',21,4)     
OUTFIL FNAMES=SORTOUT,VTOF,BUILD=(1,35)

does.

hchinnam,

Quite simple . Your Input is a VB file and you did not account for the RDW (4 bytes) . So the actual positions of the include field is 31.

The second case worked because you converted the VB file to FB file which does NOT have the RDW.

use the following control cards . I assumed that you did not account for RDW on all the fields in your INREC card too

Code:

//SYSIN   DD *
  INCLUDE COND=(31,4,CH,GE,C'0300',AND,31,4,CH,LE,C'0701')
  INREC FIELDS=(1,4,C' ',37,16,C' ',372,5,PD,TO=ZD,LENGTH=8,C' ',25,4) 
  SORT FIELDS=(27,4,ZD,A)                                                 
  OUTFIL VTOF,BUILD=(1,35)

hchinnam,

You thought wrong. Check this link which explains in in detail about the order of processing in DFSORT

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ICE1CA20/1.5.4

If you notice the control cards I posted , it follows the order of processing
