[CDG5] MPW code mysteries

[Max Poliakovski]

Daniel, thanks a lot! I could try that out although I'm afraid it won't
work as expected. To my understanding, every object module produced by
whatever tool contains its own TOC. PPCLink will finally merge all TOCs
from all objects in a way we have no control over. The question is how to
put a symbol at the start of the data section to ensure that it will end up
at the start of the data section of the linked object?
