For windows, an espec has the form

wname , ekeyword , etype

where

    ekeyword::= expr V │
│
│		 BEVENT
EVENT		 │
│
│

For gadgets, an espec has the form

wname , gkeyword , gname , ekeyword , etype

For timers, an espec has the form

wname , tkeyword , tname , ekeyword , etype

For menu choices, an espec has the form

wname , mkeyword , mname , ckeyword , item , ekeyword , etype

All other forms of espec are reserved.

Event specification attributes, identified by especattributes, determine when events and call backs occur.

    especattribute::= expr V │
