<!--- Use <cfoutput> for simple values such as strings, numbers, and expressions --->
<cfoutput>#myVariable#</cfoutput> <!--- myValue --->
<cfoutput>#myNumber#</cfoutput> <!--- myValue --->

<!--- Declaring complex variables --->
<!--- Declaring an array of 1 dimension: literal or bracket notation --->
<cfset myArray1 = [] />
<!--- Declaring an array of 1 dimension: function notation --->
<cfset myArray2 = ArrayNew(1) />

<!--- Outputting complex variables --->
<cfdump var="#myArray1#" /> <!--- An empty array object --->
<cfdump var="#myArray1#" /> <!--- An empty array object --->

<!--- Operators --->
<!--- Arithmetic --->
<cfoutput>#1 + 1#</cfoutput> = 2
<cfoutput>#10 - 8#</cfoutput> = 2
<cfoutput>#1 * 2#</cfoutput> = 2
<cfoutput>#10 / 5#</cfoutput> = 2
<cfoutput>#12 % 5#</cfoutput> = 0

<!--- Comparison --->
<cfoutput>#1 eq 1#</cfoutput> <!--- TRUE --->
<cfoutput>#15 neq 1#</cfoutput> <!--- TRUE --->
<cfoutput>#10 gt 8#</cfoutput> <!--- TRUE --->
<cfoutput>#1 lt 2#</cfoutput> <!--- TRUE --->
<cfoutput>#10 gte 5#</cfoutput> <!--- TRUE --->
<cfoutput>#1 lte 5#</cfoutput> <!--- TRUE --->

<!--- Control Structures --->
<cfset myCondition = "Test" />
<cfif myCondition eq "Test">
    <cfoutput>#myCondition#</cfoutput>
<cfelseif myCondition eq "Production">
    <cfoutput>#myCondition#. Proceed Carefully!!!</cfoutput>
<cfelse>
