modules with duplicate labels (Aviation and Navigation)

[twdeckard]

Greetings, thank you all for the quick replies.

My question was based on a flawed assumption and I retract it (I think).

It was my belief that if two modules contained duplicate alpha labels for utility subroutines then executing a parent function from the ROM in the higher number port would incorrectly call the subroutine from the lower number port.

I was intending to overload the subroutine in question with one I wrote. In homage to the Apple Lisa, I would execute different operations based on the calling address and disambiguate the conflict.

However, it appears the modules address their subroutines with explicit XROM calls so I do not need to worry execution inadvertently jumps from one ROM to another?
