The ConTeXt manual tells me on page 237:
You can define your own buffer with:
\definebuffer[...]
... name
After this command /getbuffer and \typebuffer are available where
buffer is the name of the buffer.
I do:
\definebuffer[left]
\startbuffer[left]
left\crlf
\stopbuffer
\typeleft
and it gives me the error:
! Undefined control sequence.
\typeleft ->\dodotypebuffer
[left][def-3]
l.92 \typeleft
then I try:
\typebuffer[left]
this gives a typeset message [file examdoc-def-2.tmp does not exist]
(file examdoc.tex being the containing tex file)
when I try
\getbuffer[left] or \getleft
nothing at all seems to happen?
Why doesn't it work according to the manual?
Or do I misunderstand the manual completely?

If you just want to "tag" buffers, you do not need to define new ones.
You can simply do
\startbuffer[test]
Hello world
\stopbuffer
\typebuffer[test]
\getbuffer[test]
Defining new buffers is useful if you do not want to call buffers by
some other name. This does not allow you to "tag" the buffers. There
is also a bug in core-buf.tex due to which \type<buffer> did not work.
\unprotect
\def\dodefinebuffer[#1][#2]%
{\iffirstargument % else problems
\doglobal\increment\nofdefinedbuffers
\letvalue{\??bu#1\c!number}\nofdefinedbuffers
\letvalue{\??bu#1\c!paragraph}\v!no
\setevalue{\e!start#1}%
{\noexpand\dostartbuffer[#1][def-\nofdefinedbuffers][\e!start#1][\e!stop#1]}%
\setevalue{\e!get#1}%
{\noexpand\dodoprocessTEXbuffer[#1][def-\nofdefinedbuffers]}%
\setevalue{\e!type#1}%
{\noexpand\dotypebuffer[#1][def-\nofdefinedbuffers]}%
% was {\noexpand\dodotypebuffer[#1][def-\nofdefinedbuffers]}%
\getparameters[\??bu#1][#2]%
\fi}
\protect
\definebuffer[Example]
\startExample
Hello again
\stopExample
\typeExample %The above fix is needed for this.
\getExample

Hans, was this fixed. There is a typo in core-buf.tex and it is still
present in latest "updateable" version (2006.08.02).
