Example
    <!--- This example shows the use of StructUpdate. --->
    <p>This file is similar to addemployee.cfm, which is called by StructNew,
    StructClear, and StructDelete. To test this file, copy the
    &LT;CFELSEIF&GT; statement to the appropriate place in
    addemployee.cfm. It is an example of a custom tag used to add
    employees. Employee information is passed through the employee
    structure (the EMPINFO attribute). In UNIX, you must also add the Emp_ID.

    <cfswitch expression = "#ThisTag.ExecutionMode#">
      <cfcase value = "start">
       <cfif StructIsEmpty(attributes.EMPINFO)>
        <cfoutput>Error. No employee data was passed.</cfoutput>
          <cfexit method = "ExitTag">
       <cfelseIf StructFind(attributes.EMPINFO, "department") EQ "">
        <cfscript>
         StructUpdate(attributes.EMPINFO, "department", "Unassigned");
        </cfscript>
        <cfexit method = "ExitTag">
             <cfelse>
