Thanks Wolfgang. I am experimenting with your code and there has
arisen a problem. The book I am typesetting has some pages before the
text on page-1 starts (cover and so on). Therefore the code
\def\mypageref[#1]{\setpagestate[hvdm][#1]\color[red]{page=\pagenumber\ and
pageref=\pagestaterealpage{hvdm}{#1}}}
produces "page=29 and pageref=31". Not as intended. Do I change the
macro \pagestaterealpage into what macro? I tried \pagestatepage, but
that wasn't the right idea.
Now what further to change?
You can use the dataset command which lets you store other information,
e.g. the current value of the visible pagenumber.
\definedataset[hans][delay=yes]
\setupuserpagenumber[number=3]
\starttext
One\setdataset[hans][one][pagenumber=\userpagenumber]
\page[+2]
Two\setdataset[hans][two][pagenumber=\userpagenumber]
Three\setdataset[hans][three][pagenumber=\userpagenumber]
\blank
\ifnum0\datasetvariable{hans}{two}{realpage}=0\datasetvariable{hans}{one}{realpage}
The references are on the same page.
\else
The references are on different pages.
\fi
\blank
\ifnum0\datasetvariable{hans}{two}{realpage}=0\datasetvariable{hans}{three}{realpage}
The references are on the same page.
\else
The references are on different pages.
\fi
\page
\starttabulate
\NC One \NC \datasetvariable{hans}{one}{pagenumber} \NC\NR
\NC Two \NC \datasetvariable{hans}{two}{pagenumber} \NC\NR
\NC Three \NC \datasetvariable{hans}{three}{pagenumber} \NC\NR
\stoptabulate
\stoptext
