Title: Why are there two .trefbody sysvars?
Post by: EricL on November 25, 2006, 09:11:35 PM

mem locations 437 and 472 are both .trefbody.  The Wiki even lists both.

Is there some historical thing here I'm unaware of?

Mind if I kill one?  I'll preserve the one that the code translates .trefvar in hand coded bots to so as to not to break any hand-coded bots (unless they rely upon reading from the other mem location).

Are they both being updated in the same place in the code?  It might be that someone was mucking in the sysvars and made a mistake that got translated into future versions.

They are indeed.  mem location 437 is used for hand authored bots which reference .trefbody in their DNA txt files, but both locations are updated.

Don't remember any reason for that, might have been intended for something else at some point I suppose.

Simplicity! Yay! Duplicity! Nay!
