Here's what you get when you ask a question without testing first! I'm very
embarrassed to say that this question is bovine excrements. The metafun macro
PageNumber does indeed refer to \userpagenumber, so this part is answered.
However, there's still something I would like to know. Consider the following
example:
\startuseMPgraphic{back}
StartPage ;
z[1] = center Page ;
label.bot(textext("\switchtobodyfont[30pt]\startcolor[orange]" &
decimal PageNumber & "\stopcolor\ -- \startcolor[darkblue]" & decimal
NOfPages & "\stopcolor"), z[1]) ;
StopPage ;
\stopuseMPgraphic
\defineoverlay
[pageback]
[\useMPgraphic{back}]
\setupbackgrounds[page][background=pageback]
\setupuserpagenumber[state=start]
\starttext
\dorecurse{8}{\userpagenumber \input knuth\page}
\resetuserpagenumber
\dorecurse{8}{\userpagenumber \input knuth\page}
\stoptext
The PageNumber does the right thing: goes from 1 to 8, then is reset to 1
again. But NOfPages results in "16," the total number. Is there any way I can
have a metafun macro "the highest page number before \userpagenumber was reset"?
Thanks, and best
Thomas
