Subject: Re: [U2] OCONV of no affect.
I'm not looking for a programming alternate or suggestions. Just a
null conversion.
I didn't invent this situation. It's just one of the zillions of
examples that I inherit with my client's systems.
Under certain circumstances, a single data field contains multiple
types of data. This may be dependent on another field.
Thus, code like this exists:
IF REC<5>="N" THEN
PRINT OCONV(REC<6>,"MD2")
END ELSE
PRINT REC<6>
END
Sometimes both have a conversion and I do this to save typing lines:
IF REC<5>="N" THEN CONV="MD2" ELSE CONV="D2/"
PRINT OCONV(REC<6>,CONV)
So I was wondering if this 2 line example could apply to the first
example.
Thanks in advance.
(P.S. I wonder how off-topic or deviated this thread will go. I'm just
looking for a null conversion)
