- I need to change the location that one of the OS Traps goes go.
- IM detains how to do this, but under sys 7 the effect seems to be local
- to that process. Once the application that did the patch exits, the OS Trap
- went back to its old value. Is there any way to make the patch GLOBAL and
- PERSISTENT?
-
- For now I just figured out the location in memory and patched it via
- C. I doubt if the trap table always starts at location $400 in memory
- for all models though.
-
- I want to trap BlockMove to a version optimized for the 030, my SE has
- a 030 card.
