Tests if both operands have values of FALSE.
Examples
The following Not Or examples evaluate two false operands and produce a TRUE result.
SET A=0,B=0
WRITE "A'!B = ",A'!B // Returns 1
SET A=0,B=0
WRITE "'(A!B) = ",'(A!B) // Returns 1
The following Not Or examples evaluate one TRUE and one false operand and produce a result of FALSE.
SET A=0,B=1
WRITE "A'!B = ",A'!B // Returns 0
SET A=0,B=1
WRITE "'(A!B) = ",'(A!B) // Returns 0
The following Not Or (||) example evaluates the left operand, and because it is TRUE (1) does not evaluate the right operand. The Not inverts the resulting boolean value, so the expression returns FALSE (0).
SET A=1
WRITE "'(A||B) = ",'(A||B) // Returns 0
