\starttext
\def\Buffer#1#2
{
\startbuffer[#1]
\input #2
\stopbuffer
}
\Buffer{bla}{knuth}
\stoptext
-------------------------
Context gives me the following error on this:
tex error > tex error on line 9 in file C:/Users/emargraf/Documents/buffer.tex: ! Undefined control sequence
\Buffer ...startbuffer [#1] \input #2 \stopbuffer
l.9 \Buffer{bla}{knuth}
-----------------------
Kind regards
