Because REXX isn't PL/I? Because REXX isn't a scripting language?

Not even close; it was a counterexample to your claim about case insensitivity.

The statement in question was
x =value('foo.'bar'2')
It has nothing to do with a variable called BAR2, but rather a variable called
BAR.

ITYM for safety you need to use the value() BIF.

Yes, I use inline data in JCL, but a lot less than when I was dealing with
cards. Most of the inline data that I've seen in the last few decades shouldn't
have been inline.

I think I'm going to be sick!

Again, no.

Because it's the right answer to the wrong question, and has nothing to do with
the need for GLOBALV. Google for "persistent data".

THere's a lack of closure. Why can't a command (ADDRESS) environment
be implemented in Rexx?

Circuitous. And if BAR || '2' is an assigned variable you may get undesired
results.
(Try it; I think we had this discusion long ago.) For safety, you need to:
TAIL = bar'2'
X = foo.TAIL

Idiosyncratic neologism by analogy to "longjump". Imagine ITERATE X
or LEAVE X where X is not local but EXPOSEd from an enclosing procedure.

Circuitous. Why not some sort of IMPORT list or EXPOSE list so the names
could just be used as variables. As in POSIX shell.
