NAME
     help, olh - On-Line Help (OLH) service

SYNOPSIS
     help [-tty|-nw|-ascii] [keyword]
     help [-x|-motif] [-internal] [-external] [keyword]

DESCRIPTION
     _H_e_l_p invokes the On-Line Help (OLH) service, which provides
     a menu-oriented interface to documentation that is available
     in on-line form.

     OLH is available in both terminal-oriented and X based sys-
     tems.  The default is to use the X based version where there
     is an X display available.  The

     When you are using the X-based interface, the '-internal'
     and '-external' flags are used to select whether to use the
     built-in viewer when possible, and when to call external
     viewers.  External viewers have the advantage thay they will
     be able to display the help information in its original for-
     mat, but have the disadvantage of taking up much more memory
     and being slow to start up.

     The default is to use external viewers if they are available
     and the processor is sufficiently powerful to run them
     without trouble.  On the VSII and VS2000 platforms, the
     default is to use the internal platforms.  On on all other
     workstations, the default is to use the external viewers.

     For more help in using the X-based interface, look under the
     "Help" menu.

     When using the terminal-oriented interface, you can type the
     following commands:

     ?    Display help.

     _n_u_m_b_e_r
          Select the topic with the specified _n_u_m_b_e_r from the
          current menu.  This will cause another menu or a docu-
          ment to be displayed.

     +    Scroll the list of topics up.

     -    Scroll the list of topics down.

     u    Go "up" to the previous menu.

     c    Ask a Consultant for assistance.  This invokes the
          _o_l_c(1) (On-Line Consulting) service.

          To abort the keyword-entry mode, press Ctrl-G.
