June, I think Mike is developing his conferencing system as yet another server, like LISTSERV or RELAY -- note his idea for both an offline CONFER-L and an interactive, RELAY-like CONFER-C. As a server, it may be restricted (by programming limitations) to running on IBM/VM, but it ought to be able to also serve users on MVS and other hardware/software systems. /Hugh Pritchard, Systems Programming [log in to unmask] The Catholic University of America Computer Center (202) 635-5373 Washington, DC 20064 USA Disclaimer: My views aren't necessarily those of the Pope.
