In ColdFusion 8 one can use shortcuts to refer to three boolean operators: NOT, AND, OR

NOT can also be used to as !

AND can also be used as &&

OR can also be used as ||

<cfset x = 10>

<cfset y = 30>



<cfoutput>

x = #x#<br/>

y = #y#

</cfoutput>



<!--- Reverse the value of an argument. For example, NOT True is False and vice versa. --->

<p><strong>Using NOT or !:</strong> Testing for !x eq y </p>

<cfif !x eq y>

   x is not equal to y

<cfelse>

   x is equal to y

</cfif>



<p><strong>Using AND or &&</strong>: Testing for x eq 10 && y eq 30</p>

<!--- Return True if both arguments are True; return False otherwise. For example, True AND True is True, but True AND False is False. --->

<cfif x eq 10 && y eq 30>

   x is equal to y

<cfelse>

   x is not equal to y

</cfif>



<p><strong>Using OR or ||</strong>: Testing for x eq 10 || y eq 20</p>

<!--- Return True if any of the arguments is True; return False otherwise. For example, True OR False is True, but False OR False is False. --->

<cfif x eq 10 || y eq 20>

   One of the values is true

<cfelse>

   None of the values are true

</cfif>

This code yields the following output.

=======Start output=======

x = 10
y = 30

Using NOT or !: Testing for !x eq y

x is not equal to y

Using AND or &&: Testing for x eq 10 && y eq 30

x is equal to y

Using OR or ||: Testing for x eq 10 || y eq 20

One of the values is true

=======End output=======

The other boolean operators -- XOR, EQV, IMP -- continue to work as before.
