Hi,

I have two enumerations:

\defineenumeration [exercici] You need a different name for the normal enumeration environment, e.g. exercicidefault [alternative=serried,text={\startcolor[middlecyan]Exercici\stopcolor},stopper={.\space},left={\bgroup},right={\egroup},width=fit,headstyle=\ss]

\defineenumeration [exercicivora] [alternative=serried,text={\startcolor[middlecyan]Exercici\stopcolor},stopper={.\space},left={\bgroup\startframedtext[background=screen,frame=off,width=broad]},right={\stopframedtext\egroup},width=fit,headstyle=\ss]

I just want to join into one: when I do \startexercici ... \stopexercici ConTeXt do the first, and when I pass \startexercici[vora] ... \stopexercici then do the second. That is, 'vora' as optional argument.

How can I achieve that?

You have to write you own version of the exercise environment which chooses one the two enumerations dependent on the argument.

\def\startexercici {\dosingleempty\dostartexercici}

\def\dostartexercici[#1]% {\edef\currentexercici{#1}% \doifelse{\currentexercici}{vora} \startexercicivora \startexercicidefault}

\def\stopexercici {\doifelse{\currentexercici}{vora} \stopexercicivora \stopexercicidefault}

Thanks Wolfgang. I note this is a little bit complicated than LaTeX define command (by me). But, thanks a lot, Xan.
