History
ColdFusion MX: Added this tag.
Usage
This tag is equivalent to a return statement within a cfscript tag. It accepts one return variable argument. To return more than one value, populate a structure with name-value-pairs, and return the structure with this tag.
To access the result value from this tag, you use the variable scope that is the value of the cfinvoke tag returnVariable attribute.
You can code a maximum of one cfreturn tag within a function.
For example code, see Chapter 11, "Building and Using ColdFusion Components," in Developing ColdFusion MX Applications.

Example

    <cfcomponent>
       <cffunction name="getEmp">
           <cfquery name="empQuery" datasource="ExampleApps" >
              SELECT FIRSTNAME, LASTNAME, EMAIL
              FROM tblEmployees
           </cfquery>
           <cfreturn empQuery>
       </cffunction>
       <cffunction name="getDept">
          <cfquery name="deptQuery" datasource="ExampleApps" >
              SELECT *
              FROM tblDepartments
           </cfquery>
           <cfreturn deptQuery>
       </cffunction>
