Event Subsystem

 The Event  Subsystem is the "home" of TCXL's input routines.  This includes
 the keyboard  bindings (which  provide functionality  similar  to  keyboard
 macros), direct  input without echo, and the internal key event queue.  All
 upper-level TCXL functions call to the Event Subsystem for user input.

 Because many  features  of  TCXL's  new  event-driven  interface  were  not
 complete at the time this documentation was prepared, complete descriptions
 of these routines are provided on disk in the file, DOC\EVTDOC.TXT.
