 Probably a typo for CSV, comma-seperated values.

 It should be rather easy to typeset csv data in table format.  The
following tentative code ignores the fact that csv data may optionally
be enclosed in "" quotes that have to be removed (to be done in
TBLentry) and that these quoted strings may contain commas themselves
(which means writing a custom version of \processcommalist instead).
Apart from that, it seems to work.  (I just felt an urge of creativism,
so I took up the challenge.)


\def\TBLentry#1{\bTD#1\eTD}
\def\TBLline#1{\bTR\processcommalist[#1]\TBLentry}

% Iterate over all the lines of text captured with \obeylines active
% command to call is first argument, is not called for empty lines
\bgroup
\obeylines
\gdef\ProcessLines#1#2{\doProcessLines{#1}#2^^M\doProcessLines}%
\gdef\doProcessLines#1#2^^M#3\doProcessLines{%
  \doifnotempty{#2}{#1{#2}}%
  \doifnotempty{#3}{\doProcessLines{#1}#3\doProcessLines}%
}%
\egroup

\def\startCSV{\bgroup\obeylines\dostartCSV}

\def\dostartCSV#1\stopCSV{%
   \bTABLE
   \ProcessLines\TBLline{#1}%
   \eTABLE
   \egroup
}


\starttext
CSV test:

\startCSV
a,b,c,d,e
1,2,3,4,5
6,7,8,9,10
some text,11,12,,14
\stopCSV

\stoptext


 Hans, what goodies of ConTeXt did I miss?  Is the above sufficiently
ConTeXtish to be wikiable?
