sorting list

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

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.

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

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]
