Hi,

I have a requirement of comparing two GDG files(File1 and File2). The two GDG files will have date in the format CCYYMMDDHHMMSS.
Example 20090625103311.

I have to compare for date in File1 is greater that date in File2. If File1 date is greater then I have to call an abend routine (we have our own abend routine) else proceed to execute the other steps.

Please help me in acheving my requirement.

Thanks
Aravind

i think its a simple compare of two file. you can you a COBOL program with the below logic...

Code:

INI-Para

read file1
read file2

PROCESS-Para

if date1 > date2
    call abend
else
    proceed further and read the files again.

Sorry guys, I should have been more specific. I want the above requirement to be implemented through JCL.

As the requirement is been posted in JCL section of the Forum, what kind of solution you are looking for-- probably SORT?

As is so often stated in the forum, JCL by itself does nothing except communicate to the processor which program is to be executed, which files are to be used for the specific DD names, and also may be used to pass parameters to the selected program.

Given that you wish to achieve this through JCL you need to specify which program you would like executed to achieve the end result.

Is there only one record in each input file?

What is the starting position, length and format of the date field?

If I show you how to get a RC=16 if the file1 date is greater, or RC=0 otherwise, do you know how to use the return codes to determine whether or not to call your routine?

Frank,

yes each file will have one record in it in the format (CCYYMMDDHHMMSS). Starting pos is 1 and End pos is 14.

For example, if File1 contains - 20090621112255 and File2 contains 20090621122250 then if I compare File1>File2 then it should abend.

Yes I know how to use return codes using COND statement to call my routine. Please let me know how to get RC=16 or RC=0 for the comparision.

Thanks
Aravind

Aravind,

Why can't you use a jobstep calling REXX program to parse two input files to check the dates and set the RC =16 or 0 based on the timestamp record in the files.

Here's a DFSORT job that will do what you asked for. If date1>date2, DFSORT will pass back RC=16. Otherwise, DFSORT will pass back RC=0.

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file1
//       DD DSN=...  input file2
//OUT DD DUMMY
//SYSIN    DD    *
  OPTION COPY
  INREC IFTHEN=(WHEN=GROUP,RECORDS=2,PUSH=(15:1,14))
  OUTFIL FNAMES=OUT,STARTREC=2,OMIT=(15,14,ZD,GT,1,14,ZD),
    NULLOFL=RC16

Frank,

Thanks for your reply. the INREC statement
INREC IFTHEN=(WHEN=GROUP,RECORDS=2,PUSH(15:1,14)) is not working and says as the statement has syntax error.

SYNCSORT FOR Z/OS 1.2.3.1R U.S. PATENTS: 4210961, 5117495 (C) 2005 SYNCSO
BANK OF AMERICA-Z/OS SYNCSORT R1.2 MARCH 2006 z/O
PRODUCT LICENSED FOR CPU SERIAL NUMBER 1630E, MODEL 2094 603 LICEN
SYSIN :
OPTION COPY 0000005
INREC IFTHEN=(WHEN=GROUP,RECORDS=2,PUSH(15:1,14)) 0000006
*
OUTFIL FNAMES=OUT,STARTREC=2,OMIT=(15,14,ZD,GT,1,14,ZD),NULLOFL=RC16 0000007
WER268A INREC STATEMENT : SYNTAX ERROR
WER211B SYNCSMF CALLED BY SYNCSORT; RC=0000

I suppose IFTHEN statement is not being recognised. please need your expertise help.

The product that you are using is SYNCSORT, not DFSORT.

These are two different products, developed and marketed by two seperate companies.

Please be aware, hopefully BEFORE you post which product you use.

ICE messages indicate DFSORT, WER messages for SYNCSORT. Hardly rocket science ......... is it icon_rolleyes.gif

Topic moved to the JCL forum for SYNCSORT solutions.

Aravind,

The below SyncSort job would produce the desired results.
Code:
//STEP0100 EXEC PGM=SORT           
//SYSOUT   DD SYSOUT=*             
//SORTJNF1 DD DSN=...  input file1 
//SORTJNF2 DD DSN=...  input file2 
//SORTOUT  DD DUMMY                 
//SYSIN    DD *                     
  JOINKEYS FILE=F1,FIELDS=(15,1,A) 
  JOINKEYS FILE=F2,FIELDS=(15,1,A) 
  REFORMAT FIELDS=(F1:1,14,F2:1,14)
  INCLUDE COND=(1,14,ZD,GT,15,14,ZD)
  SORT FIELDS=COPY                 
  OPTION NULLOUT=RC4               
If date-1 > date-2, RC=0 else RC=4

If you dont have access to a manual, request for one from Use [URL] BBCode for External Links or send a PM to Alissa Margulies(JCL Moderator). They'll help you further.
