This is at $CDBB, it's the subroutine the above code jumps to. > 6145 6 10 > 6146 5 11 Both versions in the book. > 6338 254 256 > 6342 16 17 > 6356 140 30 > 6357 254 140 > 6358 47 254 > 6359 5 47 > 6360 242 5 > 6361 0 352 Dito. > 11811 245 352 > 11812 255 352 Dito. > 16256 52 136 > 16257 204 205 Dito. BUT: The book lists more changes between "old" and "new" versions, for example at $E4ED => $24ED => 9453. This leads me to the conclusion that the "new" version from the book is indeed -05, but the "old" version is not -04 but an even earlier one. > Whoever made 'cmp -l' work that way needs to have their head > examined.
