| ADED | LD B,$09 | There are nine sectors. | ||
| DrawSectorMap_Next | ADEF | LD E,(HL) | Fetch the state of the sector... | |
| ADF0 | LD D,$00 | ...and clear D. | ||

| ADFB | LD B,$00 | Clear the high byte of the counter. | ||
| ADFD | LD HL,$AE1C | Point HL at SectorMapOffsets. | ||
| AE00 | ADD HL,BC | Add the number of the sector. | ||
| AE01 | LD C,(HL) | Fetch the offset into C. | ||
| AE02 | LD B,$01 | Use 0100 as the high byte of the offset. | ||
| AE04 | CALL ColourSectorSquare | Colour the sector using ColourSectorSquare. | ||
| AE07 | POP BC | Restore the counter... | ||
