The association type is used to designate this program as an available open view for data file objects which have a type that matches one of the association types which are set. If a data file object matches a type in a program object or program file object, the title of the program object or program file object will appear in the data file object's Open cascade of its pop-up menu.
The wpQueryAssociationType method will return the type string set by the last call to the wpSetAssociationType method.
The wpQueryAssociationFilter method can be called to determine which file title filters are used to associate data file objects to this program object.
