# AND (boolean)

### From QB64 Wiki

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

- IF
*condition***AND***condition2*

- IF

*Description:*

- If
*condition***AND***condition2*are True then the evaluation returns True. -
*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 and
**OR**cannot be used to combine command line operations. -
**A double AND syntax error may be ignored and create a QB64 compiler error!** - Not to be confused with the AND and OR numerical operations.

**Relational Operators:**

Symbol | Condition | Example Usage |
---|---|---|

< | Less than | IF a < b THEN |

> | Greater than | IF a > b THEN |

= | Equal | IF a = b THEN |

<= | Less than or equal | IF a <= b THEN |

>= | Greater than or equal | IF a >= b THEN |

<> | NOT equal | IF a <> b THEN |

*Example:* 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.

*Example:* 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.
