Performs a logical disjunction on two expressions.
result = expression1 Or expression2
Arguments
result
Any numeric variable.
expression1
Any expression.

If either or both expressions evaluate to True, result is True. The following table illustrates how result is determined:
| If expression1 is |
And expression2 is |
Then result is |

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 |
