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 -- Ing.

better test with \startlines test test \stoplines also, bufferes can be flushed verbatim, as tex, as ... while macros are sort of frozen.

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
\ifdefined\BufC … \else … \fi Sometimes \setvariables is a better method to store texts in a document.
\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).
You can use \doifelsebuffer{<buffer name>}{…}{…}. Wolfgang
