RE: Exclusive-or (was: Re: Biton/Bitoff)

Mark,

It's ugly but:

x=0
if (test1) then x=x+1
if (test2) then x=x+1
if (test3) then x=x+1
...
if x=1 then true else false

 How would you deal with additional condition groups, where you wanted the
expression to be true when only one out of n expressions is true?

 Will XOR make it as an opcode?
