Well, suppose you have a purchase order entry form where you have to add/delete/save different line items. Tipically you'll have an ADD/DELETE/SAVE submit buttons with the same name (e.g. FORM-BUTTON) but with three different values (e.g. ADD, DELETE, SAVE) to be handled by three different LISP functions. Something like : (create-input-form-dispatcher FORM-BUTTON ADD ADD-ITEM-HANDLER) (create-input-form-dispatcher FORM-BUTTON DELETE DELETE-ITEM-HANDLER) (create-input-form-dispatcher FORM-BUTTON SAVE SAVE-ITEM-HANDLER) would return three dispatchers for these three events. -- ING.
