 SLEEP [seconds%]
 
 Usage Notes
   ■ Any reference to the SLEEP statement when forms are showing causes
     Visual Basic to generate the error message, "Invalid when forms are
     showing."
 
   ■ To use the SLEEP statement with forms, you must first unload or hide any
     visible forms. See: ◄HIDE Method►  ◄UNLOAD Statement►
 
   ■ An event (such as ON COM or ON TIMER) cannot interrupt a SLEEP
     suspension unless its trapping is active when the event occurs. This
     means that trapping must have been initialized with an ON event
     statement, turned on with an event ON statement, and not have been
     disabled with an event OFF statement or an event STOP statement.
     See: ◄Error/Event Trapping Summary►
 
   ■ If seconds% is 0, omitted, or a noninteger value, the program execution
     is suspended until a key is pressed or a trapped event occurs.
 
   ■ SLEEP responds only to keystrokes that occur after it executes.
 
   ■ SLEEP ignores characters in the keyboard buffer that were typed before
     it executed.
