Re: [Re: RPGILE V4.3 Gotcha]

Hans,
What would the relative performace differences be between using this
gentleman's multiplications vs. Setting up a data structure

D Date    DS
D   DATECY    1    2    0
D    Date_Yr    3    4    0
D    Date_Mo    5    6    0
D    TestDate    1    6    0



C            If    TestDate < 199909

I would imagine that even if you used different field names in the DS that
the processing would be worlds faster since moves are generally less
expensive in terms of microprocessor time.
