.SH NAME
help, olh \- On-Line Help (OLH) service
.SH SYNOPSIS
.nf
help [-tty|-nw|-ascii] [keyword]
help [-x|-motif] [-internal] [-external] [keyword]
.fi
.SH DESCRIPTION

\fIHelp\fR 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 systems.  The default
is to use the X based version where there is an X display available.  The
'-tty' and '-motif' may be used to explicitly select an interface.

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 format,
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:
