NAME

CWAIT -- Append copper wait instruction to user copper list.

SYNOPSIS

    CWAIT( c , v , h )

    CWait( c , v , h )
           a1  d0  d1
    CBump( c )
          a1

    void CWait( struct UCopList *, WORD, WORD)

Links: UCopList

FUNCTION

Add instruction to wait for vertical beam position v and horizontal position h to this intermediate copper list.

INPUTS

c - pointer to UCopList structure v - vertical beam position (relative to top of viewport) h - horizontal beam position

RESULTS

this is actually a macro that calls CWait(c,v,h) and then calls CBump(c) to bump the local pointer to the next instruction.

BUGS User waiting for horizontal values of greater than 222 decimal is illegal.
