The issue is with your parenthesis I believe

#IF (@bsong = !@bsong) {#echo Bloodsong: @bsong}

Of course, a given variable will always be equal to itself.

( tried your idea, didn't work :( ... )
was just trying to do a basic math thing like in most programming languages...

var a = 0
a = !a
( now a is equal to 1 )
a = !a
( now a is equal to 0 again )

Ah, silly me.
We are notting the variable instead of the equal sign.

#IF (@bsong!=@bsong) {will never be true}

#IF (@bsong = 1) {@bsong = 0} {@bsong = 1}
#ECHO Bloodsong: @bsong

you define it as:
bsong=0
bsong=1
you only use the @ symbol when you want to reference the current value of bsong

further testing shows that (!0) and (!1) do return the boolean reciprocals as well

#IF (!@bsong) {bsong=0} {bsong=1}
