Thank you for the link, the answer to my question was as in the example you
gave, but with a single argument. The solution to my problem given below
works, but I can't find the answer to the following question. What is the
difference between \dosingleempty and \dosingleargument ?

%%%%%%%%%%%%%%%%%%%%%%%
\unprotect

\definesystemvariable {dt}

\def\setuptitle
  {\dosingleempty\dosetuptitle}

\def\dosetuptitle[#1]%
  {\def\dodosetuptitle##1%
     {\getparameters[\??dt][#1]}%
  \processcommalist[#1]\dodosetuptitle}

\def\placetitle
  {\startalignment[\v!middle]
   \blank[\v!force,2*\v!big]
   \@@dttitle
   \blank[3*\v!medium]
   \@@dtauthor
   \blank[2*\v!medium]
   \@@dtdate
   \blank[3*\v!medium]
   \stopalignment}

\setuptitle
  [\c!title=,
   \c!author=,
   \c!date=\currentdate]
