My earlier post did not consider dynamic system symbols. There is an excellent chart at
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.2.0/com.ibm.zos.v2r2.ieae200/dynpsm.htm listing (I suppose all) supported dynamic symbols in z/OS V2R2. Most are date related. Some of these symbols have changed over the years, but I think they are valid in V1R13. You can test these symbols in Rexx with this function: MVSVAR("symbol-name") . This function does not require any special authority. . .

So you could have a user create 365 Date datasets * hhmmss entries and then not have a process to DELETE the things no longer needed. I will use the inappropriate term - ga-zillions of datasets in your DASD Volumes and no clean up.
