This form of addressing uses two bytes 10J the offset, whereas an absolute address uses bytes: move fred(pc),d0 *this instruction is 4 bytes move. fred op* *this instruction is 6 bytes Note that normally on a Mac move. W fred,do would be illegal as all data has to be accessed as offsets. However Fantasm uses a special loader in the application creates to relocate any absolute long references. Working like this is no longer recommended in Fantasm there is really no need Program counte ...
