Hello ConTeXist. I use the \processcommalist command and at this point I would like to see if there is any possibility of using a similar command but with the custom separator. Not to me to use a comma as a separator, because I need to have a comma as a character in the processed item list. Thanks Jaroslav Hajtmar Here is my inspirative minimal example: \def\setmyownparameter#1#2{% \global\def\myparameter{#2}#1% }%% \def\processmylist[#1]#2% {\processcommalist[#1]{\setmyownparameter{#2}}} \startbuffer[mybuffer] Here I use my parameter \myparameter.\par \stopbuffer \starttext \processmylist[firstparameter, secondparameter, thirdparameter]{ \getbuffer[mybuffer] } % I would like use for example * as list separator (best option to choose any character). %\processmylist[Hello, He said.*Here is comma, used too.* And here is comma, too.]{ %\getbuffer[mybuffer] %} \stoptext
