Okay, here is the Axe starting code for an APP:
CD8B40 ;jumps to the program code
EF364C ;gets ready to exit
CD50002740 ;exits
I believe that last one can be a simple EF2740 because that bcall automatically exits (meaning you don't need to use bjump)
No, you have to use bjump here. In fact, if you didn't, it would load stuff on the stack that isn't taken off, which is bad.
