Mark,
   Here's an awk solution.
------------------------split.awk-----------------------

BEGIN{pcFile="/dev/null";}
/xxx-[0123456789]+/{close(pcFile);pcFile = $1;}
{print $0 >> pcFile;}

--------------------------------------------------------

execute it by
awk -f split.awk datafile

Hope this helps
