Although this Guide has given a number of examples of defining verbs in TADS 3, no attempt has been made to treat this topic in a systematic fashion.
For more information on defining your own verbs in TADS 3, consult the sections in the Technical Manual on 'How to Create Verbs', along with articles on 'Action Results' and 'Good use of verify() and check()'. See also the discussion on 'Controlling the Action' in Section 4 of Chapter Five of Getting Started in TADS 3, and on defining CrossAction in Chapter Six of Getting Started.
