Re: Q about RPG II level break usage

Been a very long time for me too, butI think that what those I-specs do in RPG2 is it reads the same record position into all those different fields. If I remember correctly, each of those different field names used different storage locations. IF so, and that's IF I remember it correctly, it might be a "clever" way of moving that same input character into different fields instead of using MOVE.

I'm working with some S/36 RPG II code shown below. I can "sort of"
understand the repeated definition of the field in column 66, to have more
than one name for the same byte (although the field names in column 66 are
not otherwise used in the program).


I am unclear why the L3 indicator is defined more than once for the fields.
It seems to me that a single definition of L3 would work the same.


Is this some level break idiom that I missed or am not remembering? The
programs are otherwise OK in terms of being straightforward to understand
and work with (given that they are RPG II), so I think the original
programmer must have had some specific reason for coding like this.
