BLKSIZE=3120 is covered by the Historic Preservation Act. I did submit an RCF about ALLOCATE DSNTYPE(HFS). No result yet. And an RCF about several IDCAMS topics. They said clearly they'd make "job step" vs. "jobstep" consistent, in favor of the former. But they conspicuously did not address PARM length, important now that PARMDD allows up to 32,767. I suspect Binder LONGPARM(NO) may cover it, but it might need clarification. -- gil -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Even if so, the Ref. etc. should make that clear. I have never specified DSNTYPE and PATH on the same allocation.

Re: Is HFS still a thing?
If you specify HFS as a filesystem in BPXPRMxx on z/OS V2R5 it will get rejected. The system will come up, but the mounting of HFS file systems will fail. You can also specify ZFS as a parameter in IDCAMS when defining a VSAM dataset. This replaces the Dataset type of LINEAR and obviates the need for a separate format step. The format will take place when the file system is mounted the first time.

On closely related
:
HFS
Specifies an HFS data set. Specify HFS only when the DD statement also
specifies
a DSNAME parameter.
Which you didn't. But that was TSO.

Those developers don't talk to each other, do they?
I thought that DSNTYPE=HFS was used only to create a HFS "aggregate" (?
whatever)
and is superfluous (should be mutex) when specifying PATH. And there is no
similar JCL
option for zFS -- you need to use IDCAMS.

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.'

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)
