When you say that you'd like to update it, do you mean that you'd like the RLSE
parameter to be retained for subsequent usage as well? I'm quite sure that it
is
not retained, and only applies to the usage of the data set when the DD
statement
used to write to the data set has RLSE coded.

The JCL reference says how to do it:
When coding RLSE for an existing data set, code the unit of measurement
and primary quantity as they appeared in the original request. For example,
if the original request was:
SPACE=(TRK,(100,50))
you can release unused tracks when you retrieve the data set by coding:
SPACE=(TRK,(100),RLSE)

I don't think so.

Really? I'd be surprised if that was allowed. That's not the way you coded the
space at the top of this. The "1" in that space parameter is the unit for
the
allocation.
>but that seems to say it should be "SPACE=(TRK,(pri,sec,dir))". Is that right?
Yes. It is.

I trust that this has worked for you, since you say so. I never tried it that
way. It still surprised me that this should work.
I haven't looked up SPACE parameter's syntax in decades, but for me, the second
subparameter always was primary, optionally secondary, and directory if needed,
all enclosed in paranthesis. The third subparameter is the optional "keyword"
RLSE.

You can use ISPF 3.4 with the data set listed and issue Z or F - Depending on
what you want to do.

Hmmm. Maybe SPACE=(,(,),RLSE) ?? Just a guess.
I get a message on missing positional parameter. I'd prefer not
to override the original SPACE options. Must I override, merely
to add RLSE?
Hmmm. In:

Is there a misplaced '(' there? I'm used to coding "SPACE=(TRK,pri,(sec,dir))"
but that seems to say it should be "SPACE=(TRK,(pri,sec,dir))". Is that right?
Yes, the latter is correct.

And the optional "[...]" don't seem to be nested right.
Could be a fun RCF. I hope they don't just say, "Ignore the diagram; rely on
