Hi

I have a 255 record lengh file, the first 17 chars are the key. I want to eliminate all dup records and write only a 80 record length file containing only the first 17 chars without the dups. Is this is possible?.

Thanks in advance for all the help you can provide.

Not sure how an 80 record length file can contain only the first 17 chars ... that would make it a 17 record length file. I'll assume you want the first 17 chars and blank padding up to position 80. I'll also assume that the RECFM is FB. If those assumptions are wrong, let us know the correct information.

Given those assumptions, you can use a DFSORT job like this:

Code:

//S1 EXEC PGM=ICEMAN
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=...  input file (FB/255)
//SORTOUT DD=...  output file (FB/80)
//SYSIN DD *
   SORT FIELDS=(1,17,CH,A)
   SUM FIELDS=NONE
   OUTREC FIELDS=(1,17,80:X)
/*


If you're not familiar with DFSORT and DFSORT's ICETOOL, I'd suggest reading through "z/OS DFSORT: Getting Started". It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:

www.ibm.com/servers/storage/support/software/sort/mvs/srtmpub.html

Thanks for your quick resopnse.

Yes you are right, the RECFM is FB and on the output file I want the 17 chars and blanks on the rest 63 chars so that I can have my 80 RECFM file.

I don't know much about OS/390 and I'm getting an error.

Below is my JCL.
Code:

//SORT JOB (1001),                         
//        'TSO2',                         
//        CLASS=A,                         
//        MSGCLASS=X,                     
//        MSGLEVEL=(1,1),                 
//        REGION=0M,                       
//        TIME=1440,                       
//        NOTIFY=&SYSUID                   
//S1 EXEC PGM=ICEMAN                       
//SYSOUT   DD  SYSOUT=*                   
//SORTIN   DD  DSN=@ITS.SRV1.XFSFOUT       
//SORTOUT  DD  DSN=@ITS.TEMP.SORTED,       
//             DISP=(NEW,CATLG,DELETE),   
//             SPACE=(CYL,(100,50),RLSE)   
//SYSIN DD *                               
   SORT FIELDS=(1,17,CH,A)       
   SUM FIELDS=NONE               
   OUTREC FIELDS=(1,17,80:X)     
/*                               

I'm getting the following error.

ICH70001I TSO2     LAST ACCESS AT 15:24:59 ON TUESDAY, FEBRUARY 14, 2006   
IEF344I SORT S1 SORTIN - ALLOCATION FAILED DUE TO DATA FACILITY SYSTEM ERROR
IGD17045I SPACE NOT SPECIFIED FOR ALLOCATION OF DATA SET @ITS.SRV1.XFSFOUT 
IEF272I SORT S1 - STEP WAS NOT EXECUTED.                                   

Why is it asking for space on my input file?

Thanks.

Sorry I forgot to add a couple of lines. This worked, thanks for your help.
Code:

//SORT JOB (1001),                                 
//        'TSO2',                                 
//        CLASS=A,

//        REGION=0M,                               
//        TIME=1440,                               
//        NOTIFY=&SYSUID                           
//S1 EXEC PGM=ICEMAN

juan00982,

Because you don't have disp coded for your sortin. The default disposition is (new delete delete) and hence the system is asking for space parameters.

try this job

Code:

//SORT     JOB (1001),               
//             'TSO2',               
//             CLASS=A,               
//             MSGCLASS=X,           
//             MSGLEVEL=(1,1),       
//             REGION=0M,             
//             TIME=1440,             
//             NOTIFY=&SYSUID         
//*                                   
//S1      EXEC PGM=ICEMAN             
//SYSOUT  DD SYSOUT=*                 
//SORTIN  DD DSN=@ITS.SRV1.XFSFOUT,   
//           DISP=SHR                 
//SORTOUT DD DSN=@ITS.TEMP.SORTED,   
//           DISP=(NEW,CATLG,DELETE),
//           UNIT=SYSDA,             
//           SPACE=(CYL,(100,50),RLSE)
//SYSIN DD *                         
  SORT FIELDS=(1,17,CH,A)             
  SUM FIELDS=NONE                     
  OUTREC FIELDS=(1,17,80:X)           
/*                                   


Hope this helps...

Cheers
