yeah nice toggle, B+.  reminds me of the old assembly optimization of SUB ax,ax (ie x = x - x) or XOR ax,ax (ie x = x xor x) in order to set a value to zero because it was slightly faster than a MOV ax, 0.  As Steve pointed out, there's a kind of duality between arithmetic and boolean

a tip for when you want to toggle between two values is to just XOR it by (a XOR b) ie

Code: (Select All)

value1 = 49
value2 = 21

x = value1

for i=0 to 5
    print x
    x = x xor (value1 xor value2)
