RE: looking for an example of lookahead fields

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

subject: looking for an example of lookahead fields

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?
