Hi Dillon
There is also a purely plaintex solutions for example:


% Here is Peter Olsak solution (see TBN: 
ftp://math.feld.cvut.cz/olsak/tbn/tbn.pdf - czech only)

\def\terminator{*}
\def\usethereadvalues{}
\newcount\tempnum

\def\readparameters{\tempnum=0\let\next=\readonlyone \next}
\def\readonlyone #1, {\advance\tempnum by 1 \def\param{#1}%
%        \the\tempnum - \param\par%
     \ifx\param\terminator \let\next=\usethereadvalues
     \else\expandafter\def \csname param\the\tempnum\endcsname{#1}%
     \fi\next}

\def\var#1{\csname #1\endcsname}


\starttext

% Read any number of parameters, terminator is * now
\readparameters 471-44/2007, 474-44/2007, 464-44/2007, 465-44/2007, 
461-44/2007, 472-44/2007, 473-44/2007, 475-44/2007, 469-44/2007, 
455-44/2007, AA, BBB, 124,  *, %

Parameters are now in macros \type{\var{param1}}, \type{\var{param2}}, 
\type{\var{param3}},  \dots :

\blank[big]

\dorecurse{16}{parameter \recurselevel is : \var{param\recurselevel}\crlf}


\blank[big]

% OR

% put parameters into macro:
\def\parameters{A, B, XXL, QWE, 123, Hello, End, TeX, Solution, XSE, 
Flag, Prague, Paris, New York, last value, *, }
% and now read parameters:
\expandafter\readparameters\parameters


\dorecurse{16}{parameter \recurselevel is : \var{param\recurselevel}\crlf}
