<h1 class="topictitle1">Use iSeries interfaces</h1>
<div><p>Depending on the type of connection to the iSeries™ server, and the task you need
to perform, there are several options available for iSeries interfaces. Learn how to access
and use iSeries Navigator,
the character-based interface, and the wireless clients.</p>
<div class="section"><p>There are two ways to access the iSeries server, from character-based
interfaces on an attached console or emulator session and the graphical user
interface in iSeries Navigator.
The interface you need to use depends on your connection type to the iSeries server
and the task you need to perform. In this topic, you will learn how to access
the iSeries server
from the character-based interface and some functions of this access method.</p>
</div>
<div class="section"><h4 class="sectiontitle">Character-based interface</h4><p>The character-based interface,
available from most emulator sessions or consoles, might seem unfamiliar to
people without iSeries experience.
This topic explains how to navigate the <span class="keyword">i5/OS™</span> menus
and provides some suggestions for learning to use this interface.</p>
<p>The
character-based interface is available from most consoles and emulator sessions
connected to an iSeries server,
and allows more functions than any other interface. While this type of interface
may be unfamiliar at first, it includes several easy methods for helping new
users, and a menu-based hierarchy of tasks to make finding specific functions
simple.</p>
<p>The character-based interface includes three primary displays:
navigational, input, and informational. The navigational display typically
consists of a list of menu options and a command line. You can use this to
find information or tasks on the iSeries server, and to enter control
language (CL) commands. Input displays are available when the operating system
requires information from you. Use this display to enter or change information.
Informational displays provide server information and do not allow any interaction.</p>
</div>
<div class="section"><h4 class="sectiontitle">Find functions or tasks</h4><p>All server tasks are organized
into categories accessible through the main menu. You can enter menu selections
to move through this hierarchy until you find the task you are looking for.
Different users might have different menu options available to them, depending
on the security strategy, restrictions set by the system administrator, and
the active user profile. When you have found a menu option you need to use,
you can enter commands at the <span class="uicontrol">Selection or Command</span> prompt
located at the bottom of the display. Many menu displays have a name listed
in the top-left corner of the display. This name allows you to access it using
the GO command followed by the name of the menu. For example, GO JOB instructs
the operating system to display the job menu:</p>
<br /><img src="rzal2002.gif" alt="sample menu display showing the menu name in top left corner and the selection or command prompt at the bottom of the display" /><br /></div>
<div class="section"><h4 class="sectiontitle">Get help</h4><p>The character-based interface provides
several methods for assisting users. First, online help is available for many
displays by pressing the help or F1 key. You can often get help with a particular
field or item by placing your cursor on it and then pressing the help or F1
key. When you are entering data, you can also get help by entering a ? in
a data field. Finally, the amount and type of information displayed on the
display can be controlled by changing the assistance level. The assistance
level determines what version of a display you see. Many system displays have
two different versions:</p>
<ul><li>A <dfn class="term">basic assistance level</dfn> version, which contains less information
and does not use technical terminology.</li>
<li>An <dfn class="term">intermediate-assistance level</dfn> version, which shows more
information and uses technical terms.</li>
</ul>
<p>Some fields or functions are available only on a particular version
of a display. The instructions tell you which version to use. To change from
one assistance level to another, use F21 (Select assistance level). F21 is
not available from all displays.</p>
</div>
<div class="section"><p>The Connecting to the iSeries might help you understand
the differences between these interface options, and provide some instructions
for how to use them effectively.</p>
<p>There are many interfaces available
for iSeries servers,
and the interface you use depends on the type of connection and the functions
you require. This topic includes instructions and requirements for using consoles,
wireless interfaces, and iSeries Navigator.</p>
