Re: \stopbuffer in macro

[Taco Hoekwater <taco@elvenkind.com>]

This should help:

   \def\startLST[#1]%
     {\def\stopLST{End of #1}%
      \dostartbuffer[LST][startLST][stopLST]}

This is almost the same as:

    \definebuffer[LST]
    \def\stopLST{End of LST}

Except that it is a little bit more low-level and thereby allows
an argument to \startLST. Using a local definition if \stopLST
is another trick, to lift the argument to the end of the buffer.

A less sophisticated  but clearer approach is:

    \def\startLST[#1]%
     {\def\LSTArgs{#1}%
      \dostartbuffer[LST][startLST][stopLST]}

    \def\stopLST{End of \LSTArgs}

Full example:

   \def\startLST[#1]%
     {\def\stopLST{End of #1}%
      \dostartbuffer[LST][startLST][stopLST]}

   \starttext
   \startLST[whatever]
   bla bla
   \stopLST
   alb alb
   \stoptext

You'll have to fill in the commands etc. yourself of course.
