OUTREC Arithmetic with Numeric and Constants Example

Scenario - Multiply the marks with 10 and store from 45th position.

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

Explaining Example -

1. OUTREC FIELDS=(1,48,..) copies first 48 bytes input file data as it is to output.
2. OUTREC FIELDS=(..,45,3,ZD,MUL,+10) - data starts from 45th byte of length 3 will be multiplied by +10 and stores it in the same record as a continuation.
