The MAKEARRAY method of a stem variable will return whatver subscripts you
used. If you're using the stem.0 convention then those will be numeric, but
A.['bbb']=1
A.['BBB']=2
do i over A.~MAKEARRAY
say i
end
will give alphabetic output.
However, OOREXX also has, e.g., .array, .set, classes.

Full Rexx stem enumeration would *have* to include both numeric and non-numeric
tails and would have to account for all kinds of gaps:
A.1 = "Foo"
A.17 = "Bar"
A.Notary = "Sojack"
Numeric-only, gap-less enumeration is easy to do on your own
Do i = 1 to A.0
Say A.i
End i

Those arguments name the same compound symbol,
therefore the results are identical, regardless of how
or whether BBB, BBb, etc. are defined. Consider:
Bbb = 'Wombat'
say AAA.bbb value( 'AAA.bbb' )
say AAA.BBB value( 'AAA.BBB' )

That is both how it's documented and how it works.
Otherwise, cite.

How do you refer to its members?

Have you submitted your RFE yet?
If one builds OOREXX from source on z/OS, will it easily interface
to unmodified valuable host command environments such as SDSF
and SYSCALL?
How does it report gaps in a compound symbol, e.g.:
A. = 'Foo'
drop A.42
Also:
A. = 'Foo'
Z = ''
A.Z = 'Nil'
