Hi,
The macro \card must allow the word Card to be written in the normal style.
Hans' solution works well.


To use \text with a certain style use a \mathtext.. command, e.g.

\define[1]\card
  {\m{\mathtexttf{Card}\thinspace#1}}

Hello,
How to make the macro work in the environment definition ?


Can you explain your problem with the \card.

Wolfgang

not sure what you want to achieve, maybe this?

\protected\def\card#1{\m{\mfunction{Card}\thinspace#1}}

\defineenumeration
   [définition]
   [text=Définition,
number=no,
headcommand=\groupedcommand{}{.},
style=italic]

\starttext

\startdéfinition
   Soit E un ensemble fini. Le cardinal de E, noté \card{E}, est le 
nombre d'éléments de E.


   En particulier, nous avons  \m{\card{\emptyset}=0}.
\stopdéfinition

\stoptext




Thank you
Fabrice
