% We need proper unicode:
\def\relbar{\mathrel{\smash-}} % - has the same height as + .. no clue what this refers to
%D This might change:
\permanent\protected\def\hrulefill{\leaders\hrule\hfill}
%permanent\protected\def\dotfill {\cleaders\hbox{\normalstartimath\mathsurround\zeropoint\mkern1.5mu.\mkern1.5mu\normalstopimath}\hfill}
%D These need an update:

{\nonscript
\mskip-\medmuskip
\mkern5mu
\mfunction{mod}%
\penalty900

\nonscript
\mskip-\medmuskip}
\permanent\protected\def\pmod#1%
{\allowbreak
\mkern18mu
(\mfunction{mod}\mskip\medmuskip#1)}
%D This comes from plain but I gave it a \CONTEXT\ touch. When Mikael and I are in
%D the mood we will redo them in a more modern way.
