OR Logical sum
Syntax:e1ORe2
Condition: If both e1 and e2 are “0”, the operation results in “0”, otherwise in “1.”
Status: e1 = 0, e2 = 0
e1ORe2 = 0
e1 ≠ 0, e2 = 0
e1ORe2 = 1
e1 = 0, e2 ≠ 0
e1ORe2 = 1
e1 ≠ 0, e2 ≠ 0
e1ORe2 = 1
XOR Mutually exclusive logical sum
Syntax:e1XORe2
Condition: If e1 and e2 have different values, the operation results in “1”, otherwise
in “0.”
Status: e1 = 0, e2 = 0
e1XORe2 = 0
e1 ≠ 0, e2 = 0
e1XORe2 = 1
e1 = 0, e2 ≠ 0
e1XORe2 = 1
e1 ≠ 0, e2 ≠ 0
e1XORe2 = 0
NOT Logical negation
Syntax:NOTe1
Condition: Reverses the value of data e1
Status: e1 = 0 NOTe1 = 1
e1 ≠ 0 NOTe1 = 0
EXAMPLE:
01-02OR03.GT.04
Determines the OR of the computed results of “01-02” and “03.GT.04.”
