OK, for #2:
\startsetups[sectioninfo]
§ \getmarking[sectionnumber]
\stopsetups
\setupheadertexts[\setups{sectioninfo}]
\starttext
\chapter{One}
\input knuth
\stoptext
This will give me a § in the header even on the first page. I'd like
to conditionally not show the § if there's no content in
\getmarking[sectionnumber].
I realize this is probably a basic TeX programming thing, but I
haven't yet found a resource that explains TeX as a programming
language. If you know of one, please refer me to it; I'm not trying to
waste anyone's time.
I'll cook up a minimal example of the other thing later today. It's
probably a mistake in my environment, since using the code above does
not have the problem.
Thanks again,
