Thanks for taking the time, but that doesn't actually answer the
question I asked.  It in fact answers the caveat I specifically

But I also stated that I was just using it as example of a need to
branch and how cumbersome using Goto[If] makes it.

Again, appreciate that you took the time, but really looking for an
answer to the "better way to branch" question.

Hah.  This won't work either, for the reason I asked about in my
followup question about where the "true" value of an ${IF ...}has a
colon in it and is taken to be the end of the true value and the start
of the false value.

And your ${IF ...} is missing the colon between the true and false
values but I still understood what you were getting at.
