Example

<!--- This shows the use of DE and Evaluate --->
<html>
<head>
<title>
Evaluate Example
</title>
</head>

<body bgcolor = silver>
<H3>Evaluate Example</H3>

<cfif IsDefined("FORM.myExpression")>
<H3>The Expression Result</H3>

<CFTRY>
<!--- Evaluate the expression --->
<cfset myExpression = Evaluate(FORM.myExpression)>

<!--- Use DE to output the value of the variable, unevaluated --->
<cfoutput>
<I>The value of the expression #Evaluate(DE(FORM.MyExpression))#
is #MyExpression#.</I>
</cfoutput>
