# Evaluate

The function evaluates all of its arguments, left to right, and returns the result of evaluating the last argument.

See also DE and IIf.

### Syntax

    Evaluate(string_expression1 [, string_expression2 [, ... ] ] )

##### string_expression1, string_expression2

Valid expressions to be evaluated.

### Usage

String expressions can be arbitrarily complex. Note, however, that they are somewhat more complicated to write because they are inside a string. In particular, if the string expression is double-quoted, double-quotes inside the expression must be escaped.

### Examples

    <!--- 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>
