John,
What about removing the subdirectory ? I would assume like a br14
mod,delete,delete...
Dynamic creation also would be nice somehow

nobody wants to discuss, then I have my answer).
I have an automount directory at /tmp2 . For a UNIX shell, I set all the
TMPxxx type environment variables to /tmp2/SYSUID. This makes the
default temporary UNIX subdirectory for each user to be unique. I do this
so that some hog of a user can't use up the temp space for other users.
I.e. they can only shoot themselves in their own foot, not somebody else's.
Therefore, in a batch job, I can also use
PATH='/tmp2/SYSUID/some-file.txt', ... However, what I would kind of like
to do is create a separate subdirectory for a job based on the job name. In
most shops, this would likely ensure that two concurrently running jobs
would not contend over a file name. Yes, I know that I could use
PATH='/tmp2/SYSUID/JOBNAME-some.file.txt', but I would prefer
PATH='/tmp2/SYSUID/JOBNAME/some.file.txt'. Just another personal oddity.
The problem is that there is no way to dynamically create a subdirectory
via JCL. So I was thinking that a new PATHOPTS might be useful. Something
like O_MKDIR which would tell the initiator to do the equivalent of a
mkdir -p /tmp2/SYSUID/JOBNAME and then create the file in that
subdirectory.
The only problem I can envision (and there are likely more), is that the
JCL coders decide to just make O_MKDIR a standard for use on every DD which
is for a UNIX file. Which could result in subdirectories which are not
really wanted if the JCL coder mistypes something. Of course, the internal
mkdir should be done using the RACF id / UID of the job's OWNER, and not
the initiator. Which would hopefully stop somebody from creating UNIX
subdirectories and files where they don't belong. Also, I'm not sure what
the UNIX mode bits should be for any created subdirectories. At the least,
they should be 7??. I.e. at least read-write-execute for OWNER.
In the interim, I guess I'm stuck with
'/tmp2/SYSUID/JOBNAME-some.file.txt'.

This is clearly another case of too many mad scientists, and not enough
