1 :Info: scheduler.gi: 02/26/82 scheduler
  2 
  3      The module in the system that determines when a process is to run
  4 and how long it will run.  It also notifies processes of events that
  5 have occurred such as timers, I/O events, and signals from other
  6 processes.

  8 
  9 :Info: search_rules.gi: 02/26/82 search rules
 10 
 11      A list of directories that are searched to find a command,
 12 subroutine, or data item referenced symbolically.  Each directory is
 13 examined, in order, to find the given external name.  Search rules are
 14 not used when a segment is addressed by its pathname, which explicitly
 15 specifies the directory containing the segment.
 16 
 17 
 18 :Info: segment.gi: 02/26/82 segment
 19 
 20      Basic unit of information within the Multics storage system.
 21 Each segment has access attributes, at least one name, and may contain
 22 data, programs, or be empty (null).
 23 
 24 
 25 :Info: short_name.gi: 03/05/82 short name
 26 
 27      The shortened version of a command or control argument name, used
 28 interchangeably with the full name.  The short names are listed in
 29 individual command descriptions.
 30 
 31 
 32 :Info: shriek_name.gi: 02/26/82 shriek name
 33 
 34      A name, generated from a system clock value, that is guaranteed
 35 to be different from any other name so generated (e.g.,
 36 !BBBnZNlqLQddRJg).  See the description of the unique command.
 37 
 38 
 39 :Info: snap.gi: 02/26/82 snap (to snap a link)
 40 
 41      The process of finding that segment (and entry point in the
 42 segment) that is referenced by a link pair and replacing the link pair
 43 with a pointer to that entry point.  This is part of the dynamic
 44 linking mechanism, by which external symbolic references (subroutine
 45 calls, PL/I external variables) are resolved while the program is
 46 running.
 47 
 48 
 49 :Info: source_segment.gi: 03/05/82 source segment
 50 
 51      A program that exists on line in language form.  It must be
 52 converted to an object segment by compilation before it can be
 53 executed.
 54 
 55 
 56 :Info: standard_service_system.gi: sss.gi: SSS.gi: 02/26/82 standard_system_service (SSS)
 57 
 58      A group of commands and subroutines that are provided as part of
 59 the standard Multics system.  They are located in the directories
 60 >system_library_standard, >system_library_unbundled, and
 61 >system_library_1.
 62 
 63 
 64 :Info: stack.gi: 02/26/82 stack
 65 
 66      A pushdown list where active procedures maintain private regions
 67 used for temporary variables and interprocedure communication.
 68 
 69 
 70 :Info: status_code.gi: 02/26/82 status code
 71 
 72      A value returned by a subroutine indicating either the success of
 73 or the reason for failure to accomplish the requested action.
 74 Associated with standard system error codes are certain predefined
 75 messages that tell what happened.
 76 
 77 
 78 :Info: storage_system.gi: 03/05/82 storage system
 79 
 80      The combination of hardware and software that Multics uses for
 81 storing information.  The information is grouped into segments and
 82 catalogued in directories.  See also directory_hierarchy.info.
 83 
 84 
 85 :Info: subsystem.gi: 02/26/82 subsystem
 86 
 87      A collection of programs that provide a special environment for
 88 some particular purpose, such as editing, calculation, or data
 89 management.  It may perform its own command processing, file handling,
 90 and accounting.  A subsystem is said to be closed if:
 91 
 92      1.  all necessary operations can be handled within the
 93          subsystem
 94 
 95      2.  no way exists to use the normal Multics environment from
 96          within the subsystem
 97 
 98 
 99 :Info: switch.gi: 02/26/82 switch
100 
101      A path in the I/O system through which information is sent.  (See
102 attach and detach.)
103 
104 
105 :Info: SysDaemon.gi: sysdaemon.gi: 02/26/82 SysDaemon
106 
107      One of several system service processes that perform such tasks
108 as process creation, backup, network control, and printing segments on
109 the line printer.
110 
111 
112 :Info: system_administrator.gi: 02/26/82 system administrator
113 
114      A person who has the access to register users, create projects,
115 perform accounting runs, and perform other functions necessary for the

120 
121      The directory that contains those segments and directories used
122 to control the operation of the system including the answer table, who
123 table, person name table, project PDTs, etc.
