Or Operator

Performs a logical disjunction on two expressions.

result = expression1 Or expression2

Arguments

• result
  Any numeric variable.

• expression1
  Any expression.

• expression2
  Any expression.

Remarks

If either or both expressions evaluate to True, result is True. The logical operation is not short-circuited. All expressions are evaluated.

The following table illustrates how result is determined:

If expression1 is	And expression2 is	Then result is
True	True	True
True	False	True
True	Null	True
False	True	True
False	False	False
False	Null	Null
Null	True	True
Null	False	Null
Null	Null	Null

The Or operator also performs a bitwise comparison of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:

If bit in expression1 is	And bit in expression2 is	Then result is
0	0	0
0	1	1
1	0	1
1	1	1
