Re: How to: allocate a UNIX subdirectory to SYSEXEC?

Subject: How to: allocate a UNIX subdirectory to SYSEXEC?

OK, I've been reading again and trying to think <grin>. There are some
products which can now use files in a UNIX subdirectory as if they were
members of a PDS. IIRC, HLASM and some of the compilers are in this
area. I want to try to allocate my UNIX "rexx" subdirectory on my TSO
SYSEXEC. I don't seem to be able to. I did the following at the TSO
READY prompt.

"ALLOC DDN(UNIXREXX) PATH('/home/myid/rexx') FILEDATA(TEXT) RECFM(F B)
LRECL(80)"
BPXWDYN "CONCAT (SYSEXEC,UNIXREXX)"

1) That's not supported.

2) Sometimes it works; sometimes it doesn't.

3) It never works unless the first catenand is a PDS or PDSE.

4) I may have a SUG APAR that it be made to work a greater
fraction of the time. And be supported whenever it works.
(But how can I verify this if IBMLink doesn't work.)

5) Member names must be <= 8 characters, upper case only.

6) DDLIST won't report them correctly. I submitted a PMR
on this; got WAD.

As you can see, I sympathize.

The BPXWDYN did not give any messages, but a LISTALC SYSNAMES STATUS
shows that UNIXREXX still exists and shows no changes to SYSEXEC.

CALL bpxwdyn ... ?
(not 'CALL' BPXWDYN ...)
(signal on novalue spots a lot of such oversights.)

I am on z/OS 1.6. And yes, I am insane. Oh, my purpose is a "dual path"
REXX program that can run under TSO and UNIX shell.

Reusable code in z/OS? You must be insane! (Except it's Friday.)
Heck, throw in IRXJCL and stir well.
