Hello,

a question - I'm just curious:

What is advantage (or maybe intension) of using buffers over \def?

Compare:

----
\def\BufA{This is buffer A.}

\startbuffer[BufB]
   This is buffer B.
\stopbuffer

\starttext
   \BufA
   \getbuffer[BufB]

   \ifx\BufC\undefined No buffer C.\else\BufC\fi
\stoptext
----

Both ways give the required effect.

Moreover, when using \def, I can also test its existence (maybe it's also possible with buffers, but I don't know how).

Best regards,

Lukas
