Thanks, Mojca, for your ideas! Special thanks to Hans, whose solution
seemed efficient and worked like a charm (after I made one minor
fix). I have attached to the end of this message code that works well
on *either* right pages *or* left pages. Now I'd like to extend the
code so that it would work on *both* kinds of pages. But my
experimentation has raised the following questions:
1. When I change the \setupbackgrounds [page][background=thepage] in
the code shown below to \setupbackgrounds [rightpage]
[background=thepage], I expected that the left page would have no
header and the right page would have the appropriate header. However,
when I do this, I get two superimposed headers with different lengths
on right pages (and nothing, as expected, on left pages). Why do I
get *two* headers on the right page?
2. I also do not understand \startsetups command, which I could not
find in the ConTexT manual or in the online summary of ConTexT
commands. It looks like the purpose of this command is to put a
wrapper around the \setlayerframed command so that it can be used in
the \setupheadertexts command. Is this right? Also:
a. I guess that I don't understand why the \setlayerframed
command could not be used directly in the \setupheadertexts command:
why do we need the wrapper?
b. And why this particular wrapping command? (\startfoo ...
\stopfoo doesn't work.)
c. Also, I am assuming that the colon is simply part of the name
assigned to this setup and has no other significance: is this right?
3. So, my guess (once problem 1 is fixed), is that I will define
*two* layers (one for right pages and one for left pages), and do a
\setupbackground [rightpage][background=therightpage] and a
\setupbackground[leftpage][background=theleftpage]. But I don't know
what to do inside the \startsetup ... \stopsetup. Do I have a pair of
\setlayerframed statements? Do I surround this pair with something
like an if onRightPage ... if onLeftPage statement? Or do I put the
if-then statements *inside* the \setlayerframed statement?
Thanks for any help...
