issue in skipping records...

Postby SIREESHA » Mon Feb 16, 2009 12:53 pm

I'm using Sync Tool to copy first 100 records and last 500 records of a file to a output file.
I have the folowing code:

//S1 EXEC PGM=SYNCTOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN1 DD DISP=SHR,DSN=---
//OUT1 DD DISP=SHR,DSN=----
//TOOLIN DD *
SUBSET FROM(IN1) TO(OUT1) OUTPUT KEEP FIRST(100) LAST(500)
/*

but this code is not working.

I would like to know an alternative for SUBSET command.

Hello and welcome to the forum,

When you have a question, you should start a new topic for your question rather than reply to some other topic.

What release of Syncsort s used on your system?
Hope this helps,

SIREESHA,

SUBSET is supported in SyncSort for z/OS 1.3.2.0 (SYNCTOOL release 1.6.2). When you say that the code is not working, what error message are you getting? If it is a syntax error, I suspect that you are running an earlier release of the product.

I would recommend that you upgrade to the current version of SyncSort for z/OS, which will include the support for the new SYNCTOOL features.

Hello,

If you use the sort to simply "copy" the file and direct the output of the copy to a DD DUMMY, the output will show the record count. . .

"Very large" has different meanings in different environments. We'd probably all agree that a billion records is very large. How about 1million or 10 million? Some places have no files that big while 100 million is about average for several of the processes i support. . .
Hope this helps,

Sireesha,

Assuming that the file is FB/80, try this code:

//SYSIN DD *                                                   
   INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),           
         IFTHEN=(WHEN=(81,8,ZD,LE,100),OVERLAY=(81:C'99999999')) 
   SORT FIELDS=(81,8,ZD,D),EQUALS                               
   OUTFIL ENDREC=600,OUTREC=(1,80)
