I don't just think, I _know_ they work, in every Xy3+ version I retain.
And have worked, as long as I can remember.

No hurry! My goodness, it's only a "giant step forward"... I assumed that
you were aware of nested conditionals, since they occur in several of your
own current (9/98) XyWhiz routines: e.g. !EZ (where label  is
right in the middle of a nest), or !W (the second ). And several
others, I forget which. On the other hand, there are so many
mismatched/unbalanced  statements in these files, that it's a
wonder to me that EDITOR can parse the programs at all! (Mostly extra
EndIfs, e.g. in !NYC, !V^, !W, !W_W, and others -- !^V was another one, or
maybe ^!V or something, such oblivious filenames!) My programs almost
alway malfunction seriously when conditionals aren't precisely balanced.
Anyway, I guess nesting here is just inadvertent (given that it's "no
use")...

Sheer nonsense. Below, and UU-attached, is a real test, which takes your
core routine and displays the current VA$ER error state at every stage of

The last (to my knowledge) Xy3+ version. For network use (but standalone
use is fine if you LOGON).

I never used it.
