.INWK SKIP 33 \ The zero-page internal workspace for the current ship \ data block \ \ As operations on zero page locations are faster and \ have smaller opcodes than operations on the rest of \ the addressable memory, Elite tends to store oft-used \ data here. A lot of the routines in Elite need to \ access and manipulate ship data, so to make this an \ efficient exercise, the ship data is first copied from \ the ship data blocks at K% into INWK (or, when new \ ships are spawned, from the blueprints at XX21). See \ the deep dive on "Ship data blocks" for details of \ what each of the bytes in the INWK data block \ represents \ \ [Show more]
