2 xor - bitwise exclusive or of a set of integers
13 Compute the bitwise exclusive or of a set of integers.
15 For one argument xor(x1) returns x1. For two arguments,
16 xor(x1,x2) returns the bitwise exclusive or of x1 and x2.
24 For more than two arguments, xor(x1,x2,x3, ..., xn) returns:
26 xor(...xor(xor(x1,x2), x3), ... xn)
29 ; print xor(2), xor(5, 3, -7, 2, 9)
33 The number of arguments is not to exceed 1024.
36 NUMBER *qxor(NUMBER *x1, NUMBER *x2)
