Call Create to instantiate a TParam object. TParam objects are usually created by the dataset that uses them to represent its field parameters.
AParams is the TParams object to which the parameter belongs.
AParamType indicates how the parameter is to be used. It becomes the value of the ParamType property.
Collection is the TParams object to which the parameter belongs.
