IBM says: 'Before z/OS V1R7, the HFS file system was the primary hierarchical
file system. As of z/OS V1R7, you can use any combination of HFS and zFS file
systems. Because zFS has higher performance characteristics than HFS and is the
strategic file system, you should migrate your HFS file systems to zFS.'
See: 'z/OS DFSMS Using Data Sets', Version 2, Release 5, p.451

Well, both JCL and the TSO/E ALLOCATE command still only take "HFS" as a value
for DSNTYPE when allocating a Unix PATH file.
E.G. for ALLOC:
ALLOC FI(MYDDNAME) PATH('/u/tsouser/file') DSNTYPE(HFS) PATHMODE(SIRUSR)
PATHOPTS(ORDONLY) FILEDATA(TEXT) PATHDISP(KEEP, KEEP)
For JCL, see here:

I just submitted an RCF on various z/OS 2.5. TSO/E publications which mention
HFS with no mention of HFS EOS.
