/*************************************************
sysmessage.rexx
Author: Jeremy Friesner (jaf@chem.ucsd.edu)
An ARexx script that sends a system message to
all clients logged in to the local AMarqueed
server.
Usage: rx sysmessage.rexx hostnames lognames message
(hostnames) should be a regular expression denoting
the hostnames of the client or clients to be messaged.
(e.g. sdcc8.ucsd.edu or #?.edu)
(lognames) should be a regular expression denoting
the lognames of the AMarquee client or clients to
be messaged (e.g. #?Netris or QAmiTrack).
(message) Should be the message you want to send.
Example: rx sysmessage.rexx #? #? The system is shutting down!
Note that you must have given localhost
AMARQUEED_SENDSYSMESSAGE privilege in order for
this script to work.
