Well, it wouldn't need to know which ROM if it was calling if it called 
it from within the same ROM, IYSWIM. The next question is, is it ever 
used from outside the BASIC ROM? And the answer is, I doubt it very 
much, and my reason for thinking that is that the various versions of 
BASIC would be incompatible with each other if this were the case.
