See, I knew this would get into theology!
I guess I wasn't clear enough: I only meant this for when you're doing a single
instruction, something that will never expand-this
kind of "flyby" of a control block on the way to another. Clearly if you're
doing a bunch, it makes more sense to do

I would use the first method, because it is more understandable for users* that
don't have deep knowledge of both HLASM syntax and what the base field name is
in the DSECTs.

Ask ChatGPT to convert an HLASM program (you supply) to C. My guess is that it

The latter seems great when the field names are super short like
PSATOLD-PSA or TCBJSCB-TCB as in your example.
Modern control block field names are often much,
I cined the term Artificial Stupiditiy (AS) for such code.

R9? I might believe R0.
In general, I prefer the code with USING over the code with explicit offset and
base, although I might use the second if I'm only going to reference a single

control block, I would prefer to

In this specific case (and others like it), I'd probably use the latter

The second method is better; it's shorter (no USINGs). Simpler is better.

I do both. I have the USING when I either want multiple fields from the
same DSECT or I want to reference the same field(s) multiple times rather
than storing them myself somewhere. This latter is mainly when I am writing
"pure" code, such as in LPA and am short on dynamic storage.
