Dear list,
I have seen the use of blocks mechanism with and without a start/stop combination.
It is not clear to me in which cases it is required to also include a start/stop combination in this mechanism.
\beginquestion
\startquestion
Question A
\stopquestion
\endquestion
\beginanswer
\startanswer
Answer A
\stopanswer
\endanswer
Regards,
Jan Willem Flamma

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
