Thanks Hraban. I actually started out with just one setting for the
height, but have been adding more to see if I could achieve what ought
to be a very simple result by changing some of the others Nothing has
worked so far, even when I vary the choice of what to switch on and
off. The most intriguing is:
height=522.6275pt
with which I have been tinkering endlessly. I don't really see why I
need this at all since it should be automatically calculated from the
other settings, but it does make a difference, though in an unexpected
way. If I make just a minute alteration (plus or minus) I can achieve
39 lines or 41 lines, but never 40, on the first few pages. There is no
logical reason I can think of in any case why three pages should be
correct and three incorrect, but I'll keep at it until it comes right.
I had already found \showgrid but I can't use grid setting throughout
the books I am intending to set with ConTexT since a typical page will
consist at least of main text with 12 points between the lines and
footnotes with 9 points between the lines, and often also extended
quotations with 11 points between the lines. But I will need to ensure
that all pages come to the same depth.
The "lines" setting always works with the current bodyfontsize and isn’t
suited for changing font sizes (i.e. changing interlinespacing). That
you can’t seem to achieve exactly 40 lines is probably due to some
paragraph breaking penalties.
It makes no sense to set "height" or anything else in nanometer accuracy.
Just in case:
– height includes header and footer and their distances
- it’s not possible to define \textheight directly
– width is just the line width without margins
- you can also just define margings, header and footer and set height
and width to "fit".
Generally I got the impression that you’re trying to use ConTeXt with a
plain TeX mindset. That works only if you know ConTeXt in depth as well
as TeX. (If you try to tune a computer with a soldering iron, you need
to know it very well…) I can’t help you on that level, I’m just a
longtime user with a media designer’s mindset.
