Chuck,
Thanks for extending the usefulness of that i-descr. I tend to
favor i-descr's without @n references so that they can be used as a
reference in another i-descr. The @n references and semicolons sure
make it more readable, but you are then limited to replicating the logic
in another i-descr rather than just referencing the original one.
But that may be what Bob's actually looking for, trying to limit
reuse of the logic...?

Now let's generalize it a bit. Suppose the final answer is a string
instead of numeric.
You can replace the outer
02: SUM(MULS(...))
with
o2: CONVERT(@VM,'',IFS(...,'')
as follows:

Of course, we're still left with the problem of maintainability.
