Thank you very much, Bill, for pointing me in the right direction. I made the
mistake of only looking for "variable" in the index, not for <variable> as a syntax term.
Unfortunately, nobody has yet ventured to answer my other questions. I would like

Are there are any people brave, or foolish, enough to make an attempt?
