- I am not positive but two years ago at MacHack during the forum discussing
- "the correct way to write any kind of INIT" that was headed by several
- Apple employees, I could have sweared that I thought I heard a panelist
- mention that there was a reserved way to patch than involved setting a
- value in memory. I vaguely feel that it was setting a LoMem to a special
- value befor calling SetTrapAddress or something higher up on the stack.
-
- Anyway I'll bet Apple has some official ways to patch just about anything
- in system seven internally. Or at least I'd wish they did.
