Some things I do not understand about sorting:

This is the example: \def\sortprocess#1{{\bf #1}} \definesorting[city][cities][\callupcities] \setupsorting[city][criterium=all,command=\sortprocess] \city{Londen} \city{Berlijn} \city{New York} \city{Parijs} \city{Amstelveen} \placelistofcities \callupcities

question 1. The manual states (p.163) "When we add a command in the third argument during the definition of the sorted list we may recall sorted list with this command." However \callupcities gives me this error: Runaway argument? ! Paragraph ended before \callupcities was complete. <to be read again> \par

\callupcities takes an argument, that is what is causing the error message. But how it is supposed to work, I do not know.

question 2. The command \sortprocess does work, the items are in bold. But they now are typeset next to one another instead of each one on a line by itself, as occurs without command=\sortprocess on the setup.

You have to extend \sortprocess if you want something besides making a bold inlined list of cities. Why? Consider this idiom: \def\citylist{} \def\makecitylist#1{\doglobal\appendtocommalist{#1}\citylist} \setupsorting[city][criterium=all,command=\makecitylist] Cheers, Taco
