DEBUG BIN8 ? %00001111 ^ %10101001 ' Show result of XOR (%10100110)

The And Not operator (&/) returns the bitwise AND NOT of two values.

Each bit of the values is subject to the following logic:

0 AND NOT 0 = 0

0 AND NOT 1 = 0

1 AND NOT 0 = 1

1 AND NOT 1 = 0

The result returned by &/ will contain 1s in any bit positions in which the

first value is 1 and the second value is 0. Example:

SYMBOL value1 = B2

SYMBOL value2 = B3

SYMBOL result = B4

value1 = %00001111

value2 = %10101001

result = value1 &/ value2

DEBUG %result ' Show result of AND NOT (%00000110)

The Or Not operator (|/) returns the bitwise OR NOT of two values. Each

bit of the values is subject to the following logic:

0 OR NOT 0 = 1

0 OR NOT 1 = 0

1 OR NOT 0 = 1

1 OR NOT 1 = 1

The result returned by |/ will contain 1s in any bit positions in which the

first value is 1 or the second value is 0. Example:

SYMBOL value1 = B2

SYMBOL value2 = B3

SYMBOL result = B4

value1 = %00001111

value2 = %10101001

result = value1 |/ value2
