Syntax

expr1 Imp expr2

Elements

expr1, expr2

Any expressions. Their values must lie within the range for Long values.

The following table explains how LotusScript determines the result of the Imp operation.

expr1	expr2	Result
TRUE	TRUE	TRUE
TRUE	FALSE	FALSE
FALSE	TRUE	TRUE
FALSE	FALSE	TRUE
TRUE	NULL	NULL
NULL	TRUE	TRUE
FALSE	NULL	TRUE
NULL	FALSE	NULL
NULL	NULL	NULL

In addition to performing a logical implication, the Imp operator compares identically positioned bits in two numeric expressions (known as a bit-wise comparison) and sets the corresponding bit in the result according to the following table.

Bit n in expr1	Bit n in expr2	Bit n in result
1	1	1
1	0	0
0	1	1
0	0	1

Example

Dim youCanSee As Boolean, lightIsOn As Boolean

' You don't need the light to see.

youCanSee = TRUE

lightIsOn = FALSE

Print youCanSee Imp lightIsOn          ' Prints False

' You need the light to see.

youCanSee = FALSE

lightIsOn = FALSE

Print youCanSee Imp lightIsOn          ' Prints True
