result Required; any numeric variable.
expression1 Required; any expression.
expression2 Required; any expression.

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

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:
