Martin, Unless something changed since the last time I looked at this ... You cannot rename a dataset on tape. 1) Your tape management system probably wouldn't like it. 2) The physical tape label info can not be changed after the tape has been created.
AFAIK, your only way to "rename a tape dataset" is to copy it to a new tape.

They are doing this with ICEGENER copy steps. Each monthly file is a different GDG. Rather than do the actual copying I'd like them to explore using some form of rename. In this case it boils down to renaming FILE1(0) to FILE2(+1). IDCAMS ALTER will do it with hardcoded generations and versions. I checked this and that the structure of the target GDG was intact - by coding some JCL on my own system. However, I'd prefer not to have to recommend absolute generations and versions. Does anyone know how to do this with (0) and (+1)? Yes, I'm aware there may be some operational difficulties with this approach - we didn't keep n generations this way. I'm not convinced the customer actually wants to. I want to present them with options.
