==== Description ====
Turns on the next numerical layer in the background area specified by ''A''. For example, if background area 3 is currently set to display layer 1 for that particular area, a call to BGROL(0,3) will display layer 2 for that area. If an invalid layer is given, or the background rolls past the last layer for this area, no background is displayed by this opcode.
