The syntax is identical to that of \add. As for an example of use, you
could consider the following (taken from latin.mtx):

\setcommand\topaccent#1#2#3{
   \push
      \moveup{\max{0}{\sub{\height{#1}}{\int{xheight}}}}
      \movert{\add{\sub{\scale{\width{#1}}{#3}}{\scale{\width{#2}}{500}}}
         {\scale{\sub{\height{#1}}{\int{xheight}}}{\int{italicslant}}}}
      \glyph{#2}{1000}
   \pop
   \glyph{#1}{1000}
}

There is a \max on the third line.
