"C people" ... sounds like the "gettext" aficionados I butted heads with.
Sorry. I'm venting.
What to them was tedium (they didn't like "the mainframe way" of message
formatting) in my mind was just rigor and due diligence.
I do confess that this enumerated items thingy looks way better than
what my friends were doing ... now more than 20 years ago.
But do they account for locale variances?

Ah ha! Ya know, I asked our C people (who are not mainframe folks) about that and was
assured "Oh, it's some big number". I should have insisted we check!
A doc suggestion: while it says it's NL_ARGMAX, it doesn't say where that's
defined or anything. Seems like it might give a hint?
Thanks for the response, Linda. I feel a lot better about this--it seemed like
a very basic bug to not have been caught!

hi,
As was said others, this is a C runtime issue. As seen by the runtime library
reference
(https://www.ibm.com/docs/en/zos/3.2.0?topic=functions-fprintf-printf-sprintf-format-write-data),
the maximum number of positional arguments is NL_ARGMAX. Looking at limits.h,
you can see this value is 9 and hence the library is doing what it expected.
You can always request this limit be raised through the IBM Idea’s forum, but
it doesn’t look like a bug.
Hope this helps,
