Hi,

I heard that SKIPREC=z will skip first z records from the input files.
I want a single sort card to skip records 2, 100, 500 and 550 from the input file. Can any body help me out in this regard?

dckreddy,

You can do this quite easily using the new SUBSET operator of DFSORT's ICETOOL available with z/OS DFSORT V1R5 PTF UK90013 (July, 2008) like this:
Code:

//STEP0100 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) REMOVE INPUT RRN(2) RRN(100) RRN(500) RRN(550)
/*   


For complete details on the new SUBSET function and the other new functions available with PTF UK90013, see:

Kolusu,

I'm not provided with the above said version of DFSORT'S ICETOOL.

This is what the msg displayed in the spool.

SUBSET FROM(INDD1) TO(OUTDD1) REMOVE INPUT RRN(2) RRN(40)
£
INVALID OPERATOR
OPERATION RETURN CODE: 12

Is there anyother way to skip selective records from i/p file?
Thanks in advance.

Thanks & Regards,
Suma

Hi,

you can try this
Code:
//STEP1    EXEC PGM=SORT                                               
//SYSOUT   DD SYSOUT=*                                                 
//SORTIN   DD DSN=INPUT-FILE LRECL 80                                   
//SORTOUT  DD SYSOUT=*                                                 
//SYSIN    DD *                                                         
  SORT FIELDS=COPY                                                     
  INREC OVERLAY=(81:SEQNUM,8,ZD)                                       
  OUTFIL OMIT=(81,8,ZD,EQ,+2,OR,                                       
                81,8,ZD,EQ,+40),                                       
      BUILD=(1,80)                                                     
/*

If you're using z/OS DFSORT V1R5, then you just need a PTF, not a new version. Ask your System Programmer to install z/OS DFSORT V1R5 PTF UK90013 (July, 2008) - it's free.

Note that Gerry's solution assumes your input file has RECFM=FB and LRECL=80 and would have to be changed for other attributes. The SUBSET solution can be used for any attributes without change.
