   Well, you could try using two copper lists.  The first one, for the
long frame, would load BPLxPTR = data, and then at the bottom of the
frame (or whenever you're done changing stuff) would automatically set
COP1LC to the address of the SHORT frame copper list.  THAT list would
loadd BPLxPTR = data + 80, and when done would reset COP1LC to the FIRST list's
address.


      Should work.
