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 ea

No. If you write "classic rexx" without using any of the OO stuff, (or using
only a subset of it) you can choose just to have eg:
tax.3 = 20
without anything prior
A.0
Say A.i
End i

I know this basic drill on stem variables: I can say foo. = "bar" and then
the value of foo.anything is effectively "bar".
