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

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

45 calls PL/I external variables are resolved while the program is
46 running.

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
