Than you Hans! My plan is simply to use the output of a sagemath run in this way. A run should produce several files containing TeX code. I only wanted to shorten the \startbuffer \input ... \stopbuffer sequence. Maybe this (including sagemath output) could be done differently, but this was the first (and only ;-)) idea I came up with. kind regards Erik On Wed, Mar 30, 2016 at 10:11 AM, Hans Hagen wrote:

Dear List,

please help me with my problem here ....

I - probably naively - tried the following: ------------------------

\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}

\startbuffer .. \stopbuffer is parsed special

so use:

\def\Buffer#1#2 {\setbuffer[#1]{\input #2\relax}}

\Buffer{bla}{knuth}

but i'm not sure what you gain here as it will still input tufte each time

so use:

\def\Buffer#1#2 {\setbuffer[#1]{\input #2\relax}} \def\Buffer#1#2% {\setbuffer[#1]\input{#2}\endbuffer}
