I have a FB file and the LRECL is 80 bytes. I want to sort this file using date value. The date value (MMDDYY) is from column 4 to 9.
Could you please tell me how to sort date value using SYNCSORT?

Code:
  SORT FIELDS=(8.2.CH.A.4.2.CH.A.6.2.CH.A)


You can always take the CHs out by using FORMAT=CH outside the brackets.

or

Code:

//SYMNAMES DD *
DATE-YEAR,8,2,CH,A
DATE-MONTH,4,2,CH,A
DATE-DAY,6,2,CH,A
//SYSIN DD *
  SORT FIELDS=(DATE-YEAR,DATE-MONTH,DATE-DAY)


It is much more typing, I know, but it gives you (and future maintainers) a much better idea of what is happening.

Is this your first Sort?

EDIT: swapped the DD/MM around....

Hi Bill,

Thank you very much for your quick response. The problem is the year might be from 80 (1980) to 11 (2011). Is there any way to convert year from YY to YYYY before sorting?
I mean if YY is >79 then YYYY is 19YY else 20YY.

Hi,

this should help
Code:
//STEP001  EXEC PGM=SORT                                     
//SORTIN   DD *                                               
   010280                                                     
   122712                                                     
   061511                                                     
/*                                                           
//SORTOUT  DD SYSOUT=*                                       
//SYSOUT   DD SYSOUT=*                                       
//SYSIN    DD *                                               
  SORT FIELDS=(81,8,BI,A)                                     
  INREC IFTHEN=(WHEN=(8,2,ZD,GT,79),                         
       OVERLAY=(81:C'19',8,2,4,2,6,2)),                       
     IFTHEN=(WHEN=NONE,                                       
       OVERLAY=(81:C'20',8,2,4,2,6,2))                       
/*

If you have SYNCSORT version 1.3 and above, use this one -

Code:
SORT FIELDS=(1,6,Y2W,A),CENTWIN=80
