Hi,

I have the following minimal not-working example:

\starttext \startitemize \item One \startmode[modeA] \item Two \startitemize \startmode[modeB] % <- this \item Two A % <- does \stopmode % <- not work % \doifmode{modeB}{\item Two A} % <- this works \item Two B \stopitemize \stopmode \stopitemize \stoptext

Note that both modeA and modeB are not defined and hence not enabled. When compiled with the latest version of ConTeXt MkIV, I get: Missing number, treated as zero. However, If I use the inline version \doifmode instead of the environment version \startmode \stopmode, then the example compiles without problem.

I am afraid but this may be a bug.

No, just the way tex parses, \stopmode is a delimiter so the inner \stopmode ends the outer \startmode.

Using the \doif variable doesn't have that problem.

Oh, of course! Thank you and sorry for the noise. Christoph
