 3 Syntax as a command:  linus {-control_args}

 5 
 6 Function:
 7      This command invokes linus to access an MRDS data base.  It
 8 provides both retrieval and update operations.  Data to be selected is
 9 specified via query statements.
10 
11 
12 Control arguments:
13 -abbrev, -ab
14    enables abbreviation expansion and editing of request lines.
15 -iteration, -it
16    recognizes parentheses in the request line to indicate request line
17    iteration.
18 -no_abbrev, -nab
19    disables abbreviation expansion and editing of request lines.
20    (Default)
21 -no_iteration, -nit
22    parentheses in the request line are interpreted literally (i.e.,
23    they do not cause request line iteration).  (Default)
24 
25 
26 -no_prompt, -npmt
27    turns off prompting of strings.  This control argument can be
28    overridden later (see set_mode request).  (Default is prompt)
29 -no_start_up, -nsu
30    specifies that the subsystem start_up exec_com is not to be
31    executed.
32 -profile path, -pf path
33    specifies the pathname of the profile used for abbreviation
34    expansion.  A profile suffix must be the last component to path;
35    however, the suffix need not be supplied in the command line.  This
36    control argument implies -abbrev.
37 -prompt STR
38    sets the prompting string used by linus to STR.  If STR contains
39    embedded blanks, it must be enclosed in quotes.  (Default linus
40    prompt is "linus:".)
41 
42 
43 -request STR, -rq STR
44    executes STR as a linus request line before entering the request
45    loop.
46 -start_up, -su
47    specifies that the subsystem start_up exec_com "start_up.lec" is
48    executed prior to entering the request loop.  The start_up is
49    searched for in the user's home directory, project directory, and
50    then >site.  (Default)
51 
52 
53 Notes:  By default, linus prompts the user whenever input is expected
54 (the string "linus:" is displayed at linus request level).  Refer to
55 the description of the set_mode request for information on how to turn
56 off prompting.
57 
58 Multics program_interrupt conditions are recognized and handled by
59 linus.  Thus, the user may interrupt any request and resume the linus
60 session by invoking the Multics program_interrupt command.  After the
61 program_interrupt command, linus waits for the user to type further
62 requests.
63 
64 
65 There is no data base creation facility within linus.  Those users who
66 wish to create their own data base should refer to Section 3 of the
67 Multics Logical Inquiry and Update System Reference Manual (AZ49) for
68 information on the creation of an MRDS data base.

70 After invoking linus, type "help" or "help intro" for further
71 information.
