Dear List,
I would like to insert a page using (ideally) start/stop 
instructions. The problem is that this page should be inserted only 
in a certain mode. Consulting the mailing list, I thought the 
following code was working, but it’s not ! The code is executed in 
the mode as expected, but the following instructions ("Some other 
text... » in the exemple) is not typeset.
Here is a minimal (not working!) example:
% ————————————————————————————————————
\unexpanded\def\StartQuestionsList{
\startmode[ClassRoom]  \page[yes] Here are some questions: \blank
}
\unexpanded\def\StopQuestionsList{
\page[yes] \stopmode
}
\definestartstop[Questions][
before=\StartQuestionsList,
after=\StopQuestionsList
]
\startQuestions
Question A….
Question B….
\stopQuestions
Some other text...
% ————————————————————————————————————
One of the oldest mechanism available ... blocks:

\enablemode[classroom] % comment this

\defineblock[Question]

\doifmode {classroom} {
     \keepblocks[Question]
}

\starttext

     Text A

     \beginQuestion
         Question A….
     \endQuestion

     Text B

     \beginQuestion
         Question B….
     \endQuestion

     \page

     \doifnotmode {classroom} {
         \useblocks[Question]
     }

\stoptext
