Hi all,

I m trying to remove the first record-block with the same key. The key changes with every job-run.
The key is in the digits 1-4. But the key changes every job-run. I need only the records from the first key-value.

An example:

I have one input-file:
Code:


1000 header1
1000 text1
1000 text2
1000 text3
2000 header1
2000 text1
2000 text2
2000 text3
2000 text4
3000 header1
3000 text1
3000 text2
4000 header1
4000 text1
4000 text2
4000 text3
4000 text4
4000 text5


Output1 should be:
Code:

1000 header1
1000 text1
1000 text2
1000 text3


Output2 should be:
Code:

2000 header1
2000 text1
2000 text2
2000 text3
2000 text4
3000 header1
3000 text1
3000 text2
4000 header1
4000 text1
4000 text2
4000 text3
4000 text4
4000 text5


Is this possible with dfsort or icetool?


thank you very much in advance

Here's a DFSORT/ICETOOL job that will do what you asked for. I assumed your input file has RECFM=FB and LRECL=80, but the job can be changed appropriately for other attributes.

Code:

//S1 EXEC PGM=ICEMAN
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=...  input file (FB/80)
//OUT1 DD DSN=...  output file1 (FB/80)
//OUT2 DD DSN=...  output file2 (FB/80)
//SYSIN    DD *
  OPTION COPY
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),
        IFTHEN=(WHEN=(6,7,CH,EQ,C'header1'),
                OVERLAY=(81:SEQNUM,8,ZD)),
        IFTHEN=(WHEN=NONE,
                OVERLAY=(89:SEQNUM,8,ZD,
                         81:81,8,ZD,SUB,89,8,ZD,M11,LENGTH=8))
  OUTFIL FNAMES=OUT1,INCLUDE=(81,8,ZD,EQ,+1),
    BUILD=(1,80)
  OUTFIL FNAMES=OUT2,SAVE,BUILD=(1,80)

Many many thanks. It works fantastic.
It was a very good idea with the seqnum.

Today i saw following test-cases:

There are several header-lines for a block.

An example:
Inputfile:
Code:

1000 header1
1000 header1
1000 header1
1000 text1
1000 text2
1000 text3
2000 header1
2000 text1
2000 text2
2000 text3
2000 text4
3000 header1
3000 header1
3000 text1
3000 text2
4000 header1
4000 header1
4000 header1
4000 text1
4000 text2
4000 text3
4000 text4
4000 text5


Output1 should be:

Code:

1000 header1
1000 header1
1000 header1
1000 text1
1000 text2
1000 text3


Output2 should be:

Code:

2000 header1
2000 text1
2000 text2
2000 text3
2000 text4
3000 header1
3000 header1
3000 text1
3000 text2
4000 header1
4000 header1
4000 header1
4000 text1
4000 text2
4000 text3
4000 text4
4000 text5


I tried much, but I do not have a success.

thank you very much in advance

Here is Frank's jcl modified a bit :
Code:

//STEP0001 EXEC PGM=ICETOOL
//DFSMSG   DD SYSOUT=*
//TOOLMSG  DD SYSOUT=*
//TOOLIN   DD *
  COPY FROM(IN) USING(ICE0)
/*
//IN       DD *
1000 HEADER1
1000 HEADER1
1000 HEADER1
1000 TEXT1
1000 TEXT2
1000 TEXT3
2000 HEADER1
2000 TEXT1
2000 TEXT2
2000 TEXT3
2000 TEXT4
3000 HEADER1
3000 HEADER1
3000 TEXT1
3000 TEXT2
4000 HEADER1
4000 HEADER1
4000 HEADER1
4000 TEXT1
4000 TEXT2
4000 TEXT3
4000 TEXT4
4000 TEXT5
/*
//OUTX     DD SYSOUT=*
//OUTY     DD SYSOUT=*
//ICE0CNTL DD *
  INREC IFTHEN=(WHEN=INIT,
                OVERLAY=(81:SEQNUM,5,ZD,
                         86:SEQNUM,5,ZD,RESTART=(1,4),
                         81:81,5,ZD,SUB,86,5,ZD,M11,LENGTH=5))
  OUTFIL FNAMES=OUTX,
         INCLUDE=(81,8,ZD,EQ,+0),
         BUILD=(1,80)
  OUTFIL FNAMES=OUTY,
         SAVE,
         BUILD=(1,80)


If you are picky about using ICETOOL then use this

Code:

//STEP0001 EXEC PGM=SORT
//SYSOUT   DD SYSOUT=*
//SORTIN   DD *
1000 HEADER1
1000 HEADER1
1000 HEADER1
1000 TEXT1
1000 TEXT2
1000 TEXT3
2000 HEADER1
2000 TEXT1
2000 TEXT2
2000 TEXT3
2000 TEXT4
3000 HEADER1
3000 HEADER1
3000 TEXT1
3000 TEXT2
4000 HEADER1
4000 HEADER1
4000 HEADER1
4000 TEXT1
4000 TEXT2
4000 TEXT3
4000 TEXT4
4000 TEXT5
/*
//OUTX     DD SYSOUT=*
//OUTY     DD SYSOUT=*
//SYSIN    DD *
  SORT FIELDS=COPY
  INREC IFTHEN=(WHEN=INIT,
                OVERLAY=(81:SEQNUM,5,ZD,
                         86:SEQNUM,5,ZD,RESTART=(1,4),
                         81:81,5,ZD,SUB,86,5,ZD,M11,LENGTH=5))
  OUTFIL FNAMES=OUTX,
         INCLUDE=(81,8,ZD,EQ,+0),
         BUILD=(1,80)
  OUTFIL FNAMES=OUTY,
         SAVE,
         BUILD=(1,80)

Instead of
Code:

INCLUDE=(81,8,ZD,EQ,+0),


it should be replaced per
Quote:

INCLUDE=(81,5,ZD,EQ,+0),
