For a DUMMY input data set, you need to specify a RECFM, LRECL and BLKSIZE on the DD statement, e.g.

//BNC14Y5 DD DUMMY,RECFM=FB,LRECL=500,BLKSIZE=500

Hi,

Please refer the code given below.

Code:

//SORTIN   DD *                                                         
 JUST A DUMMY RECORD                                                   
/*                                                                     
//SORTOUT   DD DSN=MYPDS.DATE           
//             DISP=(NEW,CATLG,DELETE),                                 
//             LRECL=16,RECFM=FB,                                       
//             SPACE=(CYL,(1,1),RLSE)                                   
//SYSIN    DD *                                                         
 INREC FIELDS=(&DATE1)                                                 
 SORT FIELDS=COPY                                                       


When I am executing the above step, getting the date in SORTOUT dataset.

I am NOT interested in giving "JUST A DUMMY RECORD" in SORTIN.

If I remove the "JUST A DUMMY RECORD" and give SORTIN as DUMMY with RECFM, LRECL and BLKSIZE, my SORTOUT is empty.

Can anyone tell me why DUMMY is not possible for SORTIN?

Psridhar,

When you code a DD DUMMY for a sortin , there are no records to copy. When you provided "JUST A DUMMY RECORD" there is atleast one record and you overlayed that with the date1

Try this job which will give you the current date even when using DD Dummy

Code:

//STEP0100 EXEC PGM=SORT                       
//SYSOUT   DD SYSOUT=*                       
//SORTIN   DD DUMMY,LRECL=8,RECFM=FB,BLKSIZE=8
//SORTOUT  DD DSN=MYPDS.DATE           
//            DISP=(NEW,CATLG,DELETE),                                 
//            SPACE=(CYL,(1,1),RLSE)                                   
//SYSIN    DD *                               
  SORT FIELDS=COPY                             
  OUTFIL REMOVECC,HEADER1=(DATENS=(4MD))       
/*


Hope this helps...

Cheers

Ganesh.B,

As I said in an earlier post (before you posted):

I thought that was pretty clear.
