Re: looking for an example of lookahead fields

Hi!

Suppose I have a Input Primary file that is program described and I want to
know the current record value of the field and the next record value of the
same field, is it possible to do it with a lookahead indicator?

Opps... ** replaces the indicator not NS or AA, my bad.

Charles,

That's easy. Put this in your I-SPECS directly below where you described

the

file:

I         AA  **
I                             1    1  FIELDNAME

That's all you have to do.

Anytime you reference FIELDNAME it will refer to the record which is

stored

in the input area but has not been moved to the processing area to be
processed in the normal RPG cycle.

It's the ** instead of NS or AA that denotes the field as a look ahead.

Hope that helps!

-Bill

Hi!

I'm looking for a RPG program that uses lookahead indicator ** with a
program described file. I searched on the IBM information center and I

found

no sample code using this functionality...

Is there any old programmer here that still know how to use it?
