You now have GDG.G0002V00. You allocate GDG(+1) again, you end up with GDG.G0003V00. Actually, since the GDG is cataloged at allocate time (SMS) or step end (non-SMS), the initiator has what I recall being called a "GDG bias table". I remember a zap back in the MVT days which would disable this. The logic for this was that "the relative generation number should stay the same in all the JCL statements in all the steps". So that GDG(+1) was the same generation all steps after the one in which it was created (and cataloged). This is one reason why restart is difficult without something like CA-11. When you restart a job, you must modify all the relative GDG numbers in the DD statements.
