Hi,

Our customer sends us a file with data to be processed. It contains CCYY in the first four bytes. Our program handles only the current, previous, future-1 and future-2 dates only.

Quote:

example:
Current - 2010
Previous- 2009
Future-1 - 2011
Future-2 - 2012


The data in input file appears as shown below: (LRECL:80, RECFM:FB)
Code:

2003 XXX X1X1X1X1
2003 TTT T1T1T1T1
2004 YYY Y1X1Y1T1
2005 BBB B1T1X1X2
2006 CCC C1X1Y1T1
2009 PPP P1X1C1T1
2010 GGG G1X1T1P1
2011 EEE E1T1X1Y1
2012 VVV V1P1X1T1
2013 KKK K1P1T1C1


I want only the below data in output file: (LRECL:80, RECFM=FB)
Code:

2009 PPP P1X1C1T1
2010 GGG G1X1T1P1
2011 EEE E1T1X1Y1
2012 VVV V1P1X1T1


So, the output file should contain Previous (2009), Current (2010), Future-1 (2011), and Future-2 (2012) for this year. For next year it should be Previous (2010), Current (2011), Future-1 (2012), and Future-2 (2013) and so on..........

How to get it using SORT?

TIA.

Regards.

Here's a DFSORT job that will do what you asked for:

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
DUMMY
//SORTOUT DD DSN=&&S1,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//SYSIN    DD    *
  OPTION COPY
  INREC BUILD=(DATE2P)
  OUTFIL BUILD=(C'STARTYR,+',1,3,PD0,SUB,+1,EDIT=(TTTT),80:X,/,
                C'ENDYR,+',1,3,PD0,ADD,+2,EDIT=(TTTT))
/*
//S2  EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SYMNAMES DD DSN=&&S1,DISP=(OLD,PASS)
//SORTIN DD DSN=...  input file (FB/80)
//SORTOUT DD DSN=...  output file (FB/80)
//SYSIN    DD    *
 OPTION COPY
 INCLUDE COND=(1,4,ZD,GE,STARTYR,AND,1,4,ZD,LE,ENDYR)
/*

Hi,

Thank you very much for the solution. It is working for me. I have got one doubt. Why it had to create symbols with a '+' in front of year part? What happens if just STARTYEAR,2009 was created?

Thanks.

The '+' isn't needed in this case. I tend to use it because it is needed for decimal constants in the BUILD operand, and it doesn't hurt to have the '+'.
