But "MXD" is the same as "POS" and "HI."

They're just synonyms for the same configuration of the condition flags, 
provided purely for the sake of source code readability: surely you'd 
have trouble, without profuse comments, understanding that a ZC 
condition meant "greater than" on a comparison, "positive" on a numeric 
operation, and "mixed" on a TSTBUM. The synonyms allow us to use result 
mnemonics that match what we're conceptually testing for, rather than 
just matching the actual flags.
