<h1>strcmp function</h1>
</center>
<hr>
<p>
<b>strcmp</b> will test two strings for equallity.
<pre>
Returns :
< 0 if s1 is less than s2
0 if s1 == s2
> 0 if s1 is greater than s2
</pre>
This function probably provides too much information
by indicating which string is lexicographically greater. The net result
means that the <b>strcmp</b> return code is logically incorrect because
it returns a <a href=../CONCEPT/true_false.html>FALSE</a> value
when the strings match.
