/*
This is an example of a stand-alone/inedt service.
It waits on port 10000/tcp for a pkt and send back
a formatted date.
It also opens an ARexx port called DS.10000 and waits
for messages on it as well.
The only command acccepted on the port is "QUIT".
It can also be run as an inetd service, adding the service
ds 10000/tcp
to the services database, and the inetd entry
dsc stream tcp nowait root rxs rxs path:ds.rexx
to the inedt database.
ds accempt just on optiona argument:
VERBOSE which makes ds to log the connections to syslog
dsfun.rexx is the single connection handler
ds.rexx is the client for the service
