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...
% ————————————————————————————————————


So to be clear, I would like the result in the « ClassRoom » mode to be:
% ————————————————————————————————————
Here are some questions:

Question A….
Question B….

Some other text...
% ————————————————————————————————————

Otherwise to be:
% ————————————————————————————————————
Some other text...
% ————————————————————————————————————

If you only set `ClassRoom` mode at compile time (rather than setting and unsetting it the middle of the document), then you can do:

\definebuffer[Questions]

\startmode[ClassRoom]
\define\StopQuestionsList {...}

\definestartstop[Questions][...]
\stopmode
