Hi Wolfgang,
Thank you for your suggestion, but I think I was not clear enough. In fact, I want to place the algorithm as the image.

You need also "location=middle" for the framedtext.

\defineframedtext
[algorithmframe]
[width=fit,
   location=middle,
   background=color,
   backgroundcolor=lightgray,
   framecolor=darkred,
   corner=round]

\definelines
[algorithm]
[space=on,
   before=\startalgorithmframe,
   after=\stopalgorithmframe]

\starttext

\startmakeup[standard]
\startalgorithm
Initialisation :
\math{u} prend la valeur 2\,000
\math{S} prend la valeur 2\,000
Traitement :
Pour \math{i} allant de 2 à \math{n}
     \math{u} prend la valeur \math{u\times 1,008}
     \math{S} prend la valeur \math{S +u}
Fin Pour
Sortie :
Afficher \math{S}
\stopalgorithm
\stopmakeup

\stoptext
