Hi,
My requirement is to get the last updated event from the input file.
I/p file structure:
Code:

A1-1      A2-8                      A3-37       A4-48
333507 2005-06-29-21.05.54          HALFWRKD   2005-06-29-20.58.37.35
333507 2005-06-29-21.05.54          IASLFTCD   2005-06-29-20.58.37.35
333507 2005-06-29-21.15.53          HALFWRKD   2005-06-29-20.58.37.35
333507 2005-06-29-21.15.53          IASLFTCD   2005-06-29-20.58.37.35
333508 2005-06-29-21.30.15          IDRDTL     2005-06-29-20.59.37.31
333508 2005-06-29-21.40.15          IDRDTL     2005-06-29-20.59.37.31



O/P file required:

Code:

333507 2005-06-29-21.15.53          HALFWRKD   2005-06-29-20.58.37.35
333507 2005-06-29-21.15.53          IASLFTCD   2005-06-29-20.58.37.35
333508 2005-06-29-21.40.15          IDRDTL     2005-06-29-20.59.37.31


In the above example, the event HALFWRKD occured last at the time 2005-06-29-21.15.53 (Field A2)
Ditto for rest of the events IASLFTCD and IDRDTL.
Can this be achieved using DFSORT in a single pass?

You can use the following DFSORT/ICETOOL job to do this in one pass:

Code:

//S1    EXEC  PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD DSN=...  input file
//OUT DD DSN=...  output file
//TOOLIN DD *
  SELECT FROM(IN) TO(OUT) ON(37,8,CH) FIRST USING(CTL1)
/*
//CTL1CNTL DD *
  SORT FIELDS=(37,8,CH,A,8,19,CH,D)
/*
