Wolfgang, thanks, that worked for the sample code. However, when 
extended to three fields (I need 8) the field splitting gets rather messy.

Thanks, Martin


Modified code:

\usemodule[database]
\unexpanded\def\SendMe#1#2#3{#1\crlf#2\crlf#3}

\defineseparatedlist
   [Addressen]
   [separator={;},command=\SendMe]

\starttext
\startAddressen
house1;street1;name1
house2;street2;name2
\stopAddressen
\stoptext


Result is in attached PDF (hope that's ok)
