Sets or returns a Boolean value indicating whether the handler function
returns a value (true) or not (false). If set to false, Softimage assumes there is no return
value, regardless of whether or not the implementation actually tries to return a value.
If set to true, which is the default, Softimage tries to return a value. If the command does
not actually return anything an empty Variant is returned.
