The "(+1)" would imply a new GDG entry. Existing ones would be "(0)",
"(-1)" etc., but I doubt that IDCAMS would recognize relative GDG
entries coded as "(0)","(-1)" anyway. Just my ha'pennyworth.

We have an application that generates log tapes (virtual) with a date and time stamp in the DSN. In order to process them easily in a DR or test situation, it would be nice to have some of them in a GDG. We are not z/OS 2.1 yet, so even if they are created as a GDG, they would read in LIFO order, not what's needed. Since they are tape, they cannot be renamed, so I thought defining alias entries to point to each would work. But define alias didn't work with (+1) in the name but definging them with absolute generation numbers did work:
DEFINE ALIAS(NAME(xxxx.APPLY.LOGS.G0001V00) -
RELATE(xxxx.LOG.D14140.T134117.L0045718.TAPE))
DEFINE ALIAS(NAME(xxxx.APPLY.LOGS.G0002V00) -
RELATE(xxxx.LOG.D14140.T133348.L0045717.TAPE))
DEFINE ALIAS(NAME(xxxx.APPLY.LOGS.G0003V00) -
RELATE(xxxx.LOG.D14140.T132555.L0045716.TAPE))
The define alias statements end with CC0. I can reference a generation via the G0001V00 name, but not via relative generation or all generations via the base name.

Listcat shows the GDSs are not associated with the GDG:
GDG BASE ------ xxxx.APPLY.LOGS
IN-CAT --- CATALOG.MVSD

Can Alias names be GDS's? Is there some other way to accomplish this?
thanks
