help -- Provide help on Shell and DM commands.
usage: help  [topic [subtopic]]



DESCRIPTION
     The help command provides information on shell and DM commands and
     miscellaneous system services by opening a window to display the file
     that you request.  For a list of subjects in the help library, type

     $ help index

     Access to system help files is also provided through the HELP key. This
     key opens a read-only pad on a help file using your typed input to
     construct the pathname, so the syntax is slightly different if you are
     seeking information on a subtopic.  In that case, separate the topic and
     subtopic with a slash (/) instead of a blank.  For example:

     Help on: shell/commands


ARGUMENTS
     topic (optional)
                     Specify the name of the command or topic for which you
                     desire help.

                     Default if omitted:  display introductory information

     subtopic (optional)
                     Specify the subtopic to be viewed.  For example,

                     $ help shell commands

                     displays a topical index of shell commands, while

                     $ help shell

                     displays general information about the shell.

                     Default if omitted:  no subtopic displayed.
