[NTG-context] Multi-line equation and placement of the number

2 May 2003

      Hello Context user,

I'm trying to display a multi-line equation with a single number 
aligned with the last line. According to "The TeXbook" I should use 
\eqalignno{} for that. Unfortunately, this gobbles up the number. The 
other method of aligning th parts of my long equation (\eqalign) puts 
the number in the vertical center.

How am I supposed to do this?

Kind regards,

Maarten Sneep

I found the following code, but I seriously do not understand this...

%% from math-pln.tex in ${TEXMF}/tex/context/base
\def\eqalignno#1%
   {\displ@y
    \tabskip\centering
    \halign to \displaywidth
      {\hfil$\@lign\displaystyle{##}$\tabskip\z@skip
       &$\@lign\displaystyle{{}##}$\hfil\tabskip\centering
       &\llap{$\@lign##$}\tabskip\z@skip\crcr
       #1\crcr}}
