[Macintosh Technical Notes - 196 CDEF Parmeters]
This technical note warns writers of control definition functions
(CDEFs) of the value of the longword param parameter when the message is
drawCntl (0) or autoTrack (8). The CDEF should only consider the low
word of the param parameter when dealing with these messages.
