Re: NOOPT D-Spec keyword

[David & Eileen Keck <bstars@xxxxxxxxxxxxx>]

Bill,   If the fields in question were in the PSDS or INFDS then the problem
is the one which I related, which is documented in the RPG reference under
the NOOPT D-spec keyword.  In this case you can place the NOOPT keyword on
the those data structures, or their subfields, and the problem should be
solved.  Nevertheless, both Hans and Bob Cozzi have said that *FULL
optimization doesn't buy you anything meaningful, so the exercise is
essentially academic.
    -Dave K         ps - Thanks Hans !
