public static final int <B>SCREEN</B></PRE>
<DL>
<DD>Specifies an application-defined command that pertains to the current screen. Examples could be "Load" and "Save". A <code>SCREEN</code> command generally applies to the entire screen's contents or to navigation among screens. This is in constrast to the <CODE>ITEM</CODE> type, which applies to the currently activated or focused item or element contained within this screen. <P>Value <code>1</code> is assigned to <code>SCREEN</code>.</P></DL>

BACK</H3>
<PRE>
public static final int <B>BACK</B></PRE>
<DL>
<DD>A navigation command that returns the user to the logically previous screen. The jump to the previous screen is not done automatically by the implementation but by the <A HREF="../../../javax/microedition/lcdui/CommandListener.html#commandAction(javax.microedition.lcdui.Command, javax.microedition.lcdui.Displayable)"><CODE>commandAction</CODE></A> provided by the application.

CANCEL</H3>
<PRE>

<DL>
<DD>A command that is a standard negative answer to a dialog implemented by current screen. Nothing is cancelled automatically by the implementation; cancellation is implemented by the <A HREF="../../../javax/microedition/lcdui/CommandListener.html#commandAction(javax.microedition.lcdui.Command, javax.microedition.lcdui.Displayable)"><CODE>commandAction</CODE></A> provided by the application. <p> With this command type, the application hints to the implementation that the user wants to dismiss the current screen without taking any action on anything that has been entered into the current screen, and usually that the user wants to return to the prior screen. In many cases <code>CANCEL</code> is interchangeable with <code>BACK</code>, but <code>BACK</code> is mainly used for navigation as in a browser-oriented applications. </p> <P>Value <code>3</code> is assigned to <code>CANCEL</code>.</P><DD><DL>
