\startmode and \startcomment inside of \def

\startmode and \startcomment inside of \def

Hi,

I would like to define something like this:
\def\startSolution{\startmode[solutions]...}
\def\stopSolution{...\stopmode}

But when I use \startSolution and \stopSolution, and mode solutions isn't
enabled, I get something like
Runaway argument?
aaa \stopSolution \stoptext
! File ended while scanning use of \dostopmode.

system          > error on line 0 in file : File ended while scanning use of
\dostopmode ...

What's the proper way of doing this?

Use \startmode[...] ... \stopmode in your document without your own Solution environment or define the environment as

\definebuffer[Solution][local=yes]

\startmode[solutions]
\setupbuffer[Solution][local=no]
\stopmode

\starttext

...

\startSolution
solution
\stopSolution

...

\stoptext

How would I then do something like this?

\def\startSolution{\startmode[solutions]\startframedtext}
\def\stopSolution{\stopframedtext\stopmode}

\startmode[solution]
\setupbuffer[Solution][local=no,before=\startframedtext,after=\stopframedtext]
\stopmode

In general, I agree with Wolfgang. It is better to redefine the macro at 
an outer level. You can even do:

\defineframedtext[Solution]

\startnotmode[solution]
\definebuffer[Solution][local=yes]
\stopnotmode

However, in the few cases that you actually need to check for a mode 
inside a macro, you can use \doifmode ... etc.
