Hi Fabrice,

If you use your command \repere more often in the middle of a sentence you can slightly modify the definition of your macro in order to have a space after \repere. However, when your command is used at the end of a sentence, you have to add \unskip after your command, as in the following example:

\define\repere{$\bigl(O\,;I,J\bigr)$\space}

\starttext
\dorecurse{2}{blabla} \repere \dorecurse{2}{blabla}

Déterminer la trajectoire dans le repère \repere\unskip.

\dorecurse{2}{Blabla} \repere\ \dorecurse{2}{blabla}

\dorecurse{2}{blabla} $\bigl(O\,;I,J\bigr)$ \dorecurse{2}{blabla}

\stoptext

Best regards: OK

Hi Otared,
I did not know it because, before migrating to context, I used latex with this :  \newcommand{\repere}{$\bigl(O\,;I,J\bigr)$.
It's not very convenient to add \ every time !
Thanks,
Fabrice

Hi Fabrice,

This is a normal behaviour of TeX macro commands. You should use your command by invoking it like the following:

        \repere\ blabla blabal

Best regards: OK
