+<h1>strtoul function </h1>
+</center>
+<hr>
+<p>
+<b>strtoul</b> will convert a string to an unsigned long integer. An important 
+feature 
+of this function is the ability to accept data in various number bases
+and convert to decimal. If 
+you are just working with decimal numbers,
+<a href="atoi.html">atoi</a> is probably an easer function to use.
+<hr>
+<pre>
+Library:   stdlib.h
+
+Prototype: long int strtoul(const char *sptr, char **endptr, int base);
+
+Syntax:	   char string1[]="ff";			/* string to convert	*/
+	   int  base=16;			/* Base 16		*/
+           unsigned long int ans;		/* Result		*/
+
+           ans = strtoul(string, NULL, 16);
+</pre>
+
+<hr>
+<h2>Notes</h2>
+The first argument must not contain a + or -.<p>
+
+The second argument (char **endptr) seems to be a waste of space! If 
+it is set to NULL, STRTOL
+seems to work its way down the string until it finds an invalid character
+and then stops. All valid chars read are then converted if the string
+starts with an invalid character the function returns ZERO (0).
+<p>
+The Third argument (base) can have a value of 0 or 2-32.
+<ul>
+<li>0 - strtol will attempt to pick the base. Only Dec, Oct Hex  supported.
+<li>2-31 - The base to use.
+</ul>
