AND (boolean)

The AND (boolean) conditonal operator is used to include another evaluation in an IF...THEN or Boolean statement.

Syntax

IF condition AND (boolean) condition2

Description

• If condition AND (boolean) condition2 are true then the evaluation returns true (-1).
• condition and condition2 can also contain their own AND evaluations.
• Both the IF evaluation and the AND evaluation must be true for the statement to be true.
• Statements can use parenthesis to clarify an evaluation.
• AND (boolean) and OR (boolean) cannot be used to combine command line operations.
• Not to be confused with the AND and OR numerical operations.

Relational Operators:

Symbol	Condition	Example Usage
=	Equal	IF a = b THEN
<>	NOT equal	IF a <> b THEN
<	Less than	IF a < b THEN
>	Greater than	IF a > b THEN
<=	Less than or equal	IF a <= b THEN
>=	Greater than or equal	IF a >= b THEN

Example(s)

Using AND in an IF statement.

a% = 100
b% = 50

IF a% > b% AND a% < 200 THEN PRINT "True"

True

Explanation: Both condition evaluations must be true for the code to be executed.

Using a AND a more complex way.

a% = 100
b% = 50
c% = 25
d% = 50
e% = 100

IF (a% > b% AND b% > c%) AND (c% < d% AND d% < e%) THEN
PRINT "True"
ELSE
PRINT "False"
END IF 

True

Explanation: The evaluations in the paranteses are evaluated first then the evaluation of the paranteses takes place, since all evaluations return True the IF...THEN evaluation returns True. If any of the evaluations returned False then the IF...THEN evaluation would also return False.
