Ah, good to know. My last Mac was m68k (Performa 630CD, one of the very last m68k models), so my memories include seeing plenty of CODE resources when playing around with ResEdit.
Oh they stuck around, of course, an entire other chapter of historical MacOS zaniness in which many programs and the OS itself contained and ran both 68k and PPC code at the same time, there were 'universal procedure pointers', 'accelerated' CODE resources (with PPC code in them) and on and on.
