The HOST command is used to look up information in the
host table about a particular host name.  This information
includes the official name of the host if the name is a
nickname, the host number (in both octal and decimal),
whether the host is a user or a server, the host machine and
the host operating system.

     To use HOST, type HOST followed the host name (or any
abbreviation) you want to look for and return.  The program
will print all hosts (and nicknames) which match the input
specification.  A null specification will type out the
entire host table.  For example:

	.HOST MIT-AI		(describe MIT-AI)
	.HOST CMU		(describe all CMU sites)
	.HOST			(print out the host table)

     Note that even non-unique abbreviations are accepted.
For example "SU" will print out ALL of the Stanford
University hosts.  This is different from TELNET, etc. which
only accept abbreviations which are unique to a single host.
