Can you please let us know how the file looks like?
Ascending or descending or not in sort order? |

Hi,
try this
| Code: |
//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
0001 AAAA BBBBB
0001 AAAA BBBBB
0002 CCCC DDDD
0002 CCCC DDDD
0003 EEEE FFFFFF
/*
//SORTOUT DD DSN=&&C1,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//SYSIN DD *
OPTION COPY
OUTFIL BUILD=(80:X),REMOVECC,NODETAIL,
TRAILER1=(' OPTION COPY,SKIPREC=',COUNT-1=(M11,LENGTH=8))
/*
//S2 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
0001 AAAA BBBBB
0001 AAAA BBBBB
0002 CCCC DDDD
0002 CCCC DDDD
0003 EEEE FFFFFF
/*
//SORTOUT DD SYSOUT=*
//SYSIN DD DSN=&&C1,DISP=(OLD,PASS)

amiya_mf,
You can easily achieve this using the below SyncSort job.
| Code: |
//STEP1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTOUT DD SYSOUT=*
//SORTIN DD *
0001 AAAA BBBBB
0001 AAAA BBBBB
0002 CCCC DDDD
0002 CCCC DDDD
0003 EEEE FFFFFF
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL REMOVECC,NODETAIL,TRAILER1=(1,80) |

Hi,
Another method to crack this..
INREC OVERLAY=(81:SEQNUM,8,ZD)
SORT FIELDS=(81,8,ZD,D)
OUTFIL FILES=01,ENDREC=01,BUILD=(1,80) |

Of course this works. But I think it's less efficient because of the additional overhead in attaching the sequence number and again sorting it in descending order. |

Hello,
| Quote: |
| because of the additional overhead |
and for the sortwork dasd and cpu cycles for sorting and for the "extra" copy of the file to be written. . .
Methinks this is only an acceptable solution if your family is the hardware vendor for the organization. . .
If you only have 5 records, this might be ok, but i'd suggest most requirements have some larger volume of data. |

Amiya,
Here's a DFSORT/ICETOOL job that will do what you want for any RECFM and LRECL:
| 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

Hi
My requirement is to fetch the last record having record length = 2000. But using the below sort card getting only the 80 bytes length record.
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL REMOVECC,NODETAIL,TRAILER1=(1,80)
How can I get the full length record of 2000 bytes.
FYI :My system is not supporting SUBSET function |

Hello,
Did you try the solution Frank posted just before your question?
It mentions that it will work for any recfm/lrecl. . . |
