@Gurce Yes, sorry, I often exchanges letters by mistake. While programming, compilers usually complain about that :), so I can know, but it's not the case of human languages or names :) :) Ok, I see. Well, yes, so it would be some kind of "beauty work" to assign new "opcode names" which is certainly looks better but of course you can always write with the "manual way". Yes, there is some kind of far jump, but again, it's basically combination a "sequence of already existing opcodes". If I remember correctly, it was something like a double SED trick. In my emulator, I implemented the "linear addressing stuff", though not the "far jump" (it seems not so much uses it yet, even not kickstart).
