+<h1>GDB Debugger</h1>
+</center>
+<hr>
+<p>
+The other common debug programs on Unix systems are dbx and dbxtool.<p>
+Before a program can be processed by the debugger, it must be compiled 
+with the debugger option.
+<pre>
+	gcc -ggdb -o pipe pipe.c
+</pre>
+The program can then be passed to the debugger with
+<pre>
+	gdb pipe
+</pre>
+To pass command line parameters to the program use:
+<pre>
+	set args -size big
+</pre>
+This is equivalent to saying:
+<pre>
+	pipe -size big
+</pre>
+To single step:
+<pre>
+	break
+	run
+	step
+</pre>
+The <b>step</b> command stops execution at the next source statement,
+if that statement is a function call, gdb will single step into the function.
+<br>
+ A simular command is <b>next</b> this will also single step source 
+statements but when a it meets a function call, the function is executed 
+and gdb stops when it reaches a new source statement in the calling 
+function.
+<p>
+<b>step</b> can be abreviated to <b>s</b>
+<br>
+<b>next</b> can be abreviated to <b>n</b>
+<p> 
+To set break points:
+<pre>
+	break 48	<-- Program will stop BEFORE executing line 48
+	break FuncName  <-- Program will stop when entering the function
+	run
+</pre>
+To display the contents of a variable:
+<pre>
+	print ant[0]
+</pre>
+	
+To change the value of a variable:
+<pre>
+	set ant[0] = 4
+	set char = 'z'
+</pre>
