[Coco] replicating bitwise operators in BASIC

[Melanie and John Mark Mobley]

The following math will xor the 8-bits of A with the 8-bits of B.  I think
it is 8-bits.  In assembly its 8-bits.
Q= (NOT A AND B) OR (A AND NOT B)
QN=NOT Q
QN=(NOT A AND NOT B) OR (A AND B)

XOR is used for parity It test for even or odd.  Do you have an even number
of bits or an odd number of bits.

The following math will give a 1-bit answer.
A=1
B=0
Q=(A+B) AND 1
Q=1 if A+B is odd.
