Login and Disk Quota Procedures
-------------------------------

These types of precedures are very much installation dependent, however
some useful ideas may be gleaned from these programs.  LOGQUTBLD.COM
builds the programs.  All executables, command procedures and files are
assumed to reside in SYS$SYSTEM.  The programs LOGIN1, QUOTCHEK, LOGIN2
and LOGIN3 are run by the basic LOGIN command procedure (in that order).
TERMS.PRV lists which terminals users with privileged UIC's can login on.
SPOOLER.TRM has a list of terminals and the queue to be used as SYS$PRINT
for the terminal.  QUOTSHOW displays the users logged-out quota status and
QUOTSTAT is used in the LOGOUT procedure.  See comments at the beginning of
the programs for functional details.  The overdraft value in DEC's quota
system is used as the logged-out quota by these programs.  Users are
encouraged not to logout when over quota and are prevented from logging in
(completely) until they have reduced their disk usage.  We have found very
little conflict in this dual purpose use.  To speed up logging in the four
images executed by LOGIN.COM may be installed /OPEN/SHAR/HEAD.  Note that
LOGIN1 has the NEWSCHK program from the NEWS system built into it -
otherwise, the programs are reasonably self-contained.
