 <a name="index-pagination"></a>
 <a name="index-page-size"></a>
 <a name="index-pauses-in-output"></a>

 <p>Certain commands to <small>GDB</small> may produce large amounts of
 information output to the screen.  To help you read all of it,
 <small>GDB</small> pauses and asks you for input at the end of each page of
 output.  Type <tt class="key">RET</tt> when you want to continue the output, or <kbd>q</kbd>
 to discard the remaining output.  Also, the screen width setting
 determines when to wrap lines of output.  Depending on what is being
 printed, <small>GDB</small> tries to break the line at a readable place,
 rather than simply letting it overflow onto the following line.
 </p>
 <p>Normally <small>GDB</small> knows the size of the screen from the terminal
 driver software.  For example, on Unix <small>GDB</small> uses the termcap data base
 together with the value of the <code>TERM</code> environment variable and the
 <code>stty rows</code> and <code>stty cols</code> settings.  If this is not correct,
 you can override it with the <code>set height</code> and <code>set
 width</code> commands:
 </p>
 <dl compact="compact">
 <dd><a name="index-set-height"></a>
 <a name="index-set-width"></a>
 <a name="index-show-width"></a>
 <a name="index-show-height"></a>
 </dd>
 <dt><code>set height <var>lpp</var></code></dt>
 <dt><code>set height unlimited</code></dt>
 <dt><code>show height</code></dt>
 <dt><code>set width <var>cpl</var></code></dt>
 <dt><code>set width unlimited</code></dt>
 <dt><code>show width</code></dt>
 <dd><p>These <code>set</code> commands specify a screen height of <var>lpp</var> lines and
 a screen width of <var>cpl</var> characters.  The associated <code>show</code>
 commands display the current settings.
 </p>
 <p>If you specify a height of either <code>unlimited</code> or zero lines,
 <small>GDB</small> does not pause during output no matter how long the
 output is.  This is useful if output is to a file or to an editor
 buffer.
 </p>
 <p>Likewise, you can specify &lsquo;<samp>set width unlimited</samp>&rsquo; or &lsquo;<samp>set
 width 0</samp>&rsquo; to prevent <small>GDB</small> from wrapping its output.
 </p>
 </dd>
 <dt><code>set pagination on</code></dt>
 <dt><code>set pagination off</code></dt>
 <dd><a name="index-set-pagination"></a>
 <p>Turn the output pagination on or off; the default is on.  Turning
 pagination off is the alternative to <code>set height unlimited</code>.  Note that
 running <small>GDB</small> with the <samp>--batch</samp> option (see <a href="Mode-Options.html#Mode-Options">-batch</a>) also automatically disables pagination.
 </p>
 </dd>
 <dt><code>show pagination</code></dt>
 <dd><a name="index-show-pagination"></a>
 <p>Show the current pagination mode.
