<P>
The following conditions are available for performing numerical tests:
<font color=green>

<PRE>
     &#60;<EM>number1</EM>&#62; is above &#60;<EM>number2</EM>&#62;
     &#60;<EM>number1</EM>&#62; is not above &#60;<EM>number2</EM>&#62;
     &#60;<EM>number1</EM>&#62; is below &#60;<EM>number2</EM>&#62;
     &#60;<EM>number1</EM>&#62; is not below &#60;<EM>number2</EM>&#62;
e.g. $message_size is not above 10k
</PRE>

<P>
</font>
The &#60;<EM>number</EM>&#62; arguments must expand to strings of digits, optionally followed
by one of the letters K or M (upper-case or lower-case) which cause
multiplication by 1024 and 1024x1024 respectively.
