And operator

Performs a logical conjunction on two expressions. LotusScript rounds to the nearest integer before performing the And operation.

Syntax

expr1 And expr2

Elements

expr1, expr2

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

Usage

When using the And operator, any FALSE expression will cause the result to be FALSE.

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

Besides combining expressions, And compares identically positioned bits in two numeric expressions (known as a bit-wise comparison) and sets the corresponding bit in the result.

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

Example

' Boolean usage

Dim johnIsHere As Boolean, jimIsHere As Boolean

Dim bothAreHere As Boolean

johnIsHere = TRUE

jimIsHere = FALSE

bothAreHere = johnIsHere And jimIsHere

Print bothAreHere                 ' Prints 0 (False)

' Bit-wise usage

Dim x As Integer, y As Integer

x% = &b11110000

y% = &b11001100

Print Bin$(x% And y%)              ' Prints 11000000
