DOMAIN(7)                       Domain/OS SysV                       DOMAIN(7)



NAME
     domain - miscellaneous Domain/OS features

DESCRIPTION
     While providing all of the significant capacity of System V, Domain/OS
     SysV actually represents only a subset of the greater capacity of
     Domain/OS.  Furthermore, Domain/OS SysV omits some features of System V
     that are irrelevant to Apollo(R) workstations.  The following paragraphs
     describe visible aspects of that greater capacity.

Domain/OS Additions to the SysV Environment
     Pages that document Domain/OS-specific commands are identified with the
     heading, "Domain/OS SysV"; pages documenting standard System V UNIX
     commands are identified with the heading "SysV".

     nulm(7) passes all messages it receives, unchanged, to the next module in
     the Stream.  Messages are passed both upstream and downstream.

     nuls(7) discards all data written to it and blocks indefinitely on reads.
