The function discussed earlier is used as shown here and is appended to the set of functions already present in the functions.cfm file in the examples folder. All examples reference file - functions.cfm from which the relevant function is processed during the XMLHTTP request.
In the fourth <script/>, the _cfscriptLocation variable points to functions.cfm which also contains the function whose name is "RightangleTriangle" appended to it. The functions.cfm collects all the functions from several examples in the examples folder. An abbreviated version of functions.cfm is as shown below:
