I wish I had CA-Disk on this system. Any suggestions on how to free this space?

Well hidden in the text is: "DFSMSdss does not release any space for data sets that are empty (the last used block pointer in the data set’s VTOC entry is zero)." AFAIK, there is no way around this restriction. We use CA-DISK for that.
