Is this batch or online ?
The best method is different for each environment. |

| Then you only need a DD statement in the JCl referring to the zero generation. |

| But I just know only the GDG base name. No more information about its generations. I heard there is some 'LIST' command (in REXX) that can list the versions allocated if we give the base name. Is there something like that? |

So take a look in the JCL reference manual and look at relative generations.
The GDG base name is all that you do need to know because you can address them relatively, by latest (0), one before latest (-1) ad infinitum. |

If your goal is to get/use the latest generaton in your jcl, you do not need/want a list.

That is all you need to know - the system automatically resolves the relative generation to the specific (i.e. current, previous, etc). |
