<H1>The Console Window</H1>
<H3>Overview</H3>
<P>The Console Window is perhaps the most powerful tool in the debugger. It
provides functionality equivalent to almost all of the debugger's secondary
windows, macro definitions, and other more advanced features.</P>
<P>Console Window topics:
<UL>
<LI><UL><A HREF="#display">Console Display</A>
<LI><A HREF="#display_cmd">Executing Commands</A>
<LI><A HREF="#display_hlp">Getting Help</A>
</UL>
</UL></P>
<H3><A NAME="display">Console Display</A></H3>
The Console Display is simply a scrolled window in which the debugger prompt
appears. By default, the prompt is set to "(gdb) ", but it may be changed via a
command line option.
<P>To <A NAME="display_cmd">execute commands</A> in the console window, simply enter
the command in the display. If the debugger is busy, the message "Error: The
debugger is busy." appears informing the user that the command was not accepted.</P>
<P>Whenever a command is executed, the debugger's windows will update to display
any new state information. Any output from the command is also echoed to the Console
Window for ease of use. If an error occurs, an error message is printed to the Console
Window. All error messages appear in the Console Window using a red colored typeface.
</P>
<P>The Console Window responds to special character commands just as a shell window
does: it has a history mechanism which allows the user to scan previously used commands
by pressing the up and down arrow keys on the keyboard, jumping to the beginning or
end of a line by entering Ctrl-A or Ctrl-E, erasing a line by pressing Ctrl-K, and
more. Users familiar with GNU Emacs will recognize these keys as commonly used
keystrokes from that editor.</P>
<H3><A NAME="display_hlp">Getting Help</A></H3>
The Console Window has its own online help system. To access the help system, enter
"help" at the prompt and follow the on-screen instructions. For more help, please
consult the <!-- What is this really called? --> <I>GDB User's Guide</I>.
