- -- Abstract :
- -- The HELP System is a collection of programs which provide an interactive
- -- online documentation facility. Data for the facility is prepared as
- -- a conventional text file which is formatted in an outline form, as follows:
- --
- -- 0 Topic-Name
- -- <text of topic>
- -- 1 1st-Level-Subtopic
- -- <text of subtopic>
- -- ...
- -- 9 9th-Level-Subtopic
- -- <text>
- -- 1 2nd-1st-Level-Subtopic
- -- <text>
- -- ...
- -- 1 3rd-1st-Level-Subtopic
- -- ...
- -- 0 Next-Topic
- -- ...
- --
- -- The level numbers do not have to be consecutive, and the lower the
- -- level number is, the higher its entry appears in the hierarchy (level 4
- -- elements appear before level 6). There may be as many topics at each
- -- level as desired. A line containing only a dot (.) character causes
- -- a break between screens when the help file is displayed to the user:
- --
- -- this line appears on one screen
- -- .
- -- this line appears on the next screen (at the top)
- --
- -- The HELP System consists of three programs: HELP, HELP_BUILD, and
- -- HELP_ANALYZE.
- --
- -- The HELP program is used to display information contained in a help file.
- -- This information is in the form of a direct-access file created by the
- -- HELP_BUILD program. Briefly:
- --
- -- text of help file
- -- V
- -- HELP_BUILD
- -- V
- -- direct-access help file
- -- V
- -- HELP displays info to user
- --
- -- The HELP_ANALYZE program displays the structure hierarchy of a direct
- -- access file which is created by HELP_BUILD.
