Examples

<!--- This view-only example illustrates usage of IsStruct. --->
<P>This file is similar to addemployee.cfm, which is called
by StructNew, StructClear, and StructDelete. 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.
