BTW I notice that the functions *ldb and *dpb take the byte
specifcation shifted left by 30 (octal). This causes (ldb x y)
to expand into (*ldb (lsh x 30) y). This seems pretty gratuitous
to me since it only takes one instruction to have *ldb and *dpb
do the lsh themselves. (*ldb contains an unnecessary move anyway!)
Ah well, too late now! (snicker)
