OUTREC Data Conversion Example

DFSORT OUTREC Data Conversion Tutorial   

Scenario - Convert the first five byte ZD to FS while sorting.

Input File - MATEPK.SORT.INPUT01 - FB file of 80 length

----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8

Explaining Example -

  1. OUTREC FIELDS=(1,5,ZD,TO=FS,LENGTH=6,..) converts the first five bytes ZD from input file to FS of 6 bytes and writes it to output.
  2. 7th byte will be placed as a space in output file.
  3. OUTREC FIELDS=(..,6,73) copies the input file data from 6th byte to the output file from 8th byte onwards as it is.
