The main difference among the various flavors of EBCDIC is where the square
brackets are. The rest is mostly accented letters. Who knows how that
came about, but I'm sure it's not interesting.
There are 13 EBCDIC characters that vary across EBCDIC character map
codepages but that must always be defined when using locale settings;
here are some sample mappings:
character: [ ] { } ! \ ^ ~ ` $ | @ #
EBCDIC 1140: BA BB C0 D0 5A E0 B0 A1 79 5B 4F 7C 7B
EBCDIC 500: 4A 5A C0 D0 4F E0 5F A1 79 5B BB 7C 7B
EBCDIC 1047: AD BD C0 D0 5A E0 5F A1 79 5B 4F 7C 7B
EBCDIC 1143 B5 9F 43 47 4F 71 5F DC 51 67 BB EC 63
ASCII / UTF-8: 5B 5D 7B 7D 21 5C 5E 7E 60 24 7C 40 23

It seems that HLASM may have wandered into the code-page swamp without a
complete plan.

Yes, but what you're seeing as "[]" in your listing above is the
codepage-1047 [] characters (hex AD/BD). But the Assembler expects
codepage-037 characters. AD and BD don't correspond to printable
characters in codepage 037 (or at least not ones that HLASM seems to want
to handle; it looks to me like they're a capital Y-acute and an umlaut), so
it looks like it just leaves them alone.
Looking at:
CODEPAGE
HLASM Programmer's Guide
SC26-4941-06

.-CODEPAGE(1148|X'47C')---.
-+-------------------------+---------------------------------><
'-CODEPAGE(nnnnn|X'xxxx')-'
Default
CODEPAGE(1148|X'47C')
... and looking elsewhere, it seems that CP1148 maps AD and BD to the
same Ý and ¨. And the ISO8859-1/CP819 for those are hex DD and A8.
Why weren't the AD converted to DD and BD to A8. Where is it documented
what ASCII code page CA'...' converts to? I haven't found it yet.
Might it be because DD and A8 lie outside the USASCII half of CP819?
Is there a restriction here documented somewhere? I haven't found
it yet.
I hate EBCDIC!
