27 /* FUNCTION
28 Add a copper wait instruction to the given user copper list.
29 The copper is told to wait for a vertical beam position v and
30 a horizontal beam position h.
31 If you are using CWAIT() a call to CWait() and CBump() will
32 be made.
34 INPUTS
35 ucl - pointer to a UCopList structure
36 v - vertical beam position (relative to top of viewport)
37 h - horizontal beam position
