This was enabled. In file texmf.cnf it said:

% Enable system commands via \write18{...}?
%shell_escape = f
shell_escape = t

The testfile "test.tex":

\starttext
\immediate\write18{echo It works}
\stoptext

prints "It works" when processing the file with 'texexec --once test', 
like it says in the Metafun manual.

The other settings '\runMPgraphicstrue' and '\recycleMPslotstrue' are set 
in the virgin 'cont-sys.rme' from the distribution. It was not clear to me 
that I had to create 'cont-sys.tex' myself, since there was a very 
similarly named file already. I copied 'cont-sys.rme' to 'cont-sys.tex') 
and now it works in one run.

Thanks,

Joop
