Hi, For a GDG dataset names to have time stamp information in the name is currently not possible. What I have done to place the creation date and time into the dataset name is to use system symbols. There are dynamic system symbols in z/OS now and you can use them in JCL for name datasets. Of course the dataset is then not a GDG and you will have to create something to delete older datasets as needed. I did so using REXX with ISPF services LMDLIST etc., to create IDCAMS delete statement's for the datasets that are no longer needed to be removed. A tape management system can also give you the creation dates, if it is a tape dataset. ISPF services can be used in REXX and in other higher level programming languages. It takes some getting used to and any program using them must run in an ISPF environment.
