Hi All,

I have a file which contains 'N' recs. Could you please let me know of a way to copy only the last or nth rec onto a another file?

Thanks,
Hariharan

For the last, look at Sort step to Bring the last record to Beginning.
Fro the nth, look at SKIPREC specifies the number of records z you want to skip (delete) before starting to sort or copy the input data set.

Hariharan,

Here's a DFSORT job that will copy the last record:

Code:

//S1   EXEC  PGM=ICETOOL
//TOOLMSG   DD  SYSOUT=*
//DFSMSG    DD  SYSOUT=*
//IN DD DSN=... input file
//OUT DD DSN=...  output file
//TOOLIN DD *
SUBSET FROM(IN) TO(OUT) KEEP INPUT LAST
/*


Here's a DFSORT job that will copy the nth record. Replace n with the record number (e.g. 3):

Code:

//S2   EXEC  PGM=ICETOOL
//TOOLMSG   DD  SYSOUT=*
//DFSMSG    DD  SYSOUT=*
//IN DD DSN=... input file
//OUT DD DSN=...  output file
//TOOLIN DD *
SUBSET FROM(IN) TO(OUT) KEEP INPUT RRN(n)
/*



For complete details on the SUBSET operator of DFSORT's ICETOOL, see:

SYNCTOOL RELEASE 1.6.1 - COPYRIGHT 2007 SYNCSORT INC.
INITIAL PROCESSING MODE IS "STOP"
"TOOLIN" INTERFACE BEING USED

SUBSET FROM(IN) TO(OUT) KEEP INPUT LAST
STATEMENT DOES NOT BEGIN WITH A VALID OPERATOR
OPERATION COMPLETED WITH RETURN CODE 12

The SYT messages indicate you're using Syncsort, not DFSORT. The job works fine with DFSORT which has supported SUBSET since July, 2008.

I'm a DFSORT developer. DFSORT and Syncsort are competitive products. I'm happy to answer questions on DFSORT and DFSORT's ICETOOL, but I don't answer questions on Syncsort.

Hello,

Suggest you speak with your system support people and make sure the current release of Syncsort is installed. . .

Syncsort, Synctool, same difference.....

Assuming that the last record is uniquely identifiable by content rather than just being the last record, adding a sequence number upon input to the data records and a sequence number of zero to the date record and just sort the file by the seqnum will get you what you want.
It won't be as fast as a straight copy, but, depending on the volume of records, sort will end up with basically two strings to merge to output. And it beats going through the file twice.

To select the last record from your input file

Code:
//S1   EXEC  PGM=ICETOOL                                         
//TOOLMSG   DD  SYSOUT=*                                         
//DFSMSG    DD  SYSOUT=*                                         
//SORTIN DD DSN=..INPUT FILE                                     
//SORTOUT DD SYSOUT=..OUTPUT FILE                                 
//TOOLIN DD *                                                     
 SELECT FROM(SORTIN) TO(SORTOUT) LAST ON(81,1,CH) USING(CTL1)     
/*                                                               
//CTL1CNTL DD *                                                   
 INREC OVERLAY(81:C'1')   



To select the Nth record
Code:
//S1   EXEC  PGM=SORT                           
//SORTIN DD DSN=.....INPUT                     
//SYSOUT DD SYSOUT=*                           
//SORTOUT DD SYSOUT=*                           
//SYSIN DD *                                   
 INREC OVERLAY(81:SEQNUM,3,ZD)             N   
 SORT FIELDS=COPY                          |   
 OUTFIL FNAMES=SORTOUT,INCLUDE=(81,3,ZD,EQ,3)   
/*

Just as an FYI, support for SUBSET was included in SYNCTOOL release 1.6.2 (SyncSort for z/OS 1.3.2).

Hi Alissa,

Thanks - I was about to send you a note to ask this. I was wondering that this:
Code:
//TOOLIN DD *                                               
 SELECT FROM(SORTIN) TO(SORTOUT) LAST ON(81,1,CH) USING(CTL1)
/* 
worked while this
Code:
//TOOLIN DD *
SUBSET FROM(IN) TO(OUT) KEEP INPUT LAST
/*
not, only change was "SUBSET".
