:Info: page.gi: 02/25/82 page A 1024 36-bit word block of data within a segment. :Info: page_control.gi: 02/25/82 page control The routines that manage the transfer of pages between secondary storage and main memory frames. :Info: parent_directory.gi: 02/25/82 parent directory A parent directory is one that is immediately above, or superior, to another directory. :Info: password.gi: 02/25/82 password A character string that enables an individual user to enter the system; it is known only to that user and the program that controls access to the system. When supplied with the user's Person_id at log-in time, it validates the true identity of the user. The password is a string of one to eight characters. The characters may be any printing character from the ASCII character set except space and semi-colon. The backspace character is also allowed, and is counted as a character. The password used for interactive logins may not be "quit", "help", "HELP", or "?", because these have special meaning to the password processor. :Info: person_name_table.gi: PNT.gi: pnt.gi: 02/25/82 person name table (PNT) System table containing all Person_ids (persons and fictitious persons) registered on Multics with their encoded password, default project, address, and certain other data. :Info: Person_id.gi: person_id.gi: 02/25/82 Person_id A unique name assigned to each user of the system. It is usually some form of the user's name and contains both uppercase and lowercase characters. It may not contain blank characters. Associated with the Person_id is a single password. The Person_id and the password can be used to identify a person on several projects. :Info: physical_volume.gi: 02/25/82 physical volume A disk pack. Sometimes the combination of pack and disk drive is referred to as the physical volume. :Info: pointer.gi: 02/25/82 pointer An address value. On Multics, an address consists basically of a segment number and an offset within the segment. :Info: primary_name.gi: 02/25/82 primary name The main name associated with a segment, directory, multisegment file, or link. :Info: process.gi: 02/25/82 process The activities (programs, data entry, etc.) of an individual user that begin when the user logs in, including absentee log in, and continue until logout or until another process is explicitly begun through use of the new_proc command. :Info: process_directory.gi: 02/25/82 process directory A directory containing those segments that are meaningful only during the life of a process. These segments include the stack(s), free storage, PIT, and various temporary segments. :Info: pit.gi: PIT.gi: 02/25/82 pit (process-initialization table) The segment (in the process directory) that contains information about process initialization, i.e., Person_id and Project_id, home directory, attributes, and accounting data. :Info: process_overseer.gi: 02/01/84 process overseer A procedure called during process initialization that sets up the environment. It then returns to its caller (initialize_process_), which calls the listener to start reading commands. For more information, see process_overseer_.info. :Info: project.gi: 02/25/82 project An arbitrary set of users grouped together for accounting and access control purposes. :Info: project_administrator.gi: 02/25/82 project administrator A person who has the access to specify spending limits and other attributes for the users on a particular project. :Info: project_definition_table.gi: PDT.gi: pdt.gi: 02/25/82 PDT An administrative data base that defines all people authorized to use an account. :Info: project_master_file.gi: PMF.gi: pmf.gi: 02/25/82 project master file (PMF) An ASCII file giving the names, attributes, and account limits of the users on a particular project. It is compiled into a project definition table. :Info: Project_id.gi: project_id.gi: 02/25/82 Project_id The name assigned to a project. :Info: pure_procedure.gi: 02/26/82 pure procedure A procedure that does not modify itself. :Info: quit_request.gi: 02/26/82 quit request Several commands that read input from the keyboard use the typed request "quit" or "q" to indicate to them that the user is done. This is NOT the same as issuing the quit signal. (See quit_signal.info) :Info: quit_signal.gi: 02/26/82 quit signal A method used to interrupt a running program. The quit condition is raised by pressing the key on a terminal, such as ATTN, BRK, INTERRUPT. This condition normally causes the printing of QUIT followed by establishment of a new command level. :Info: quota.gi: 03/05/82 quota The maximum number of pages that can be used in a hierarchy of directories. Each user is allotted a predetermined amount of quota; however, quota can be increased by a system administrator. :Info: quote.gi: 02/26/82 quote A character used to delimit strings in commands and source programs. On Multics this is the double quote, ASCII octal 042, not to be confused with the single quote or apostrophe, octal 047. ----------------------------------------------------------- Historical Background This edition of the Multics software materials and documentation is provided and donated to Massachusetts Institute of Technology by Group BULL including BULL HN Information Systems Inc. as a contribution to computer science knowledge. This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology, Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL and BULL HN Information Systems Inc. to the development of this operating system. Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970), renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for managing computer hardware properly and for executing programs. Many subsequent operating systems incorporated Multics principles. Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. . ----------------------------------------------------------- Permission to use, copy, modify, and distribute these programs and their documentation for any purpose and without fee is hereby granted,provided that the below copyright notice and historical background appear in all copies and that both the copyright notice and historical background and this permission notice appear in supporting documentation, and that the names of MIT, HIS, BULL or BULL HN not be used in advertising or publicity pertaining to distribution of the programs without specific prior written permission.
