DEFINE GDG worked. Creating (+1) failed. Model DD was MODEL1 but DCB= referenced MODEL.DCB.

Is referback that picky, or was something else wrong too?

That picky. DCB=*.MODEL1 (or DCB=(MODEL1.DCB) style depending how you coded it) has to name the real DD.

Easier: point DCB= at an existing PS with the LRECL/RECFM you want. And delete leftover GDG base/gens before redefining or you fight duplicate catalog noise.

Fixed the referback. (+1) cataloged. Thanks.
