36 
37      A special type of segment that is managed by Multics supervisor
38 programs and is not directly accessible to the user.  A message

50 :Info: multiple_names.gi: 02/25/82 multiple names
51 
52      A segment, directory, multisegment file, or link can have more
53 than one name and may be referred to equally well by any one of its
54 names.  One of the names is the primary name.  A segment often has
55 more than one name because it is a program with alternate entry
56 points; commands often have short names as well as long ones for
57 convenience in typing (i.e., cwd instead of change_wdir).
58 
59 
60 :Info: multisegment_file.gi: MSF.gi: msf.gi: 02/25/82 multisegment file (MSF)
61

68      The newline, caused by typing the key labeled "RETURN" (or
69 another key designated for this purpose, such as "CR" or "LF"),
70 consists of two actions: a carriage return and a linefeed.  It is the
71 signal to Multics that a command line is ready to be processed.

77 restrict discretionary controls in order to enforce the policies of
78 the system administrator and of the organizations served by the
79 system.  The system administrator (through AIM) guarantees that only
80 authorized persons may access certain classes of information.

83 :Info: object_segment.gi: 02/25/82 object segment
84 
85      A procedure or data segment produced as the result of a
86 compilation with a system-defined format.  An executable object
87 segment can be directly executed by a process.  Object segments may
88 also be searched and linked to by the dynamic linking mechanism.
