Hi All,

This question might have asked in this forum, but I could not find by searching.

Here is the requirement. I need to generate the Sequence Numbers in output file regardless of what the value is in Input file.

Example:

INPUT FILE

002AAAUUU
005BBBKKK
007OOOWWW
025KKKMMM
412TTTEEE

I should get the output as

001AAAUUU
002BBBKKK
003OOOWWW
004KKKMMM
005TTTEEE

The first field in INPUT file is PIC S9(9) COMP. I should get Sequence Numbers starting with 1 in the same field.

I am wondering if we can do this by SORT or DFSORT. Please let me know.

Thanks

PIC S9(9) COMP is a 4-byte binary value. If you want to overlay positions 1-4 with 4-byte BI sequence numbers, you can use a DFSORT job like this:

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  OPTION COPY
  INREC OVERLAY=(1:SEQNUM,4,BI)
/*


If you really want 4-byte displayable (ZD) sequence numbers, you can use:

Code:

  INREC OVERLAY=(1:SEQNUM,4,ZD)


If you want something else, be more specific about what you want.
