### Operator ANDALSO (Short Circuit Conjunction)

Returns the short circuit-and (conjunction) of two numeric values

**Syntax:**

KeyPgDeclare declare KeyPgOperator operator

`
`

*result*=

*lhs*

**AndAlso**

*rhs*

**Parameters:**

*lhs*
The left-hand side expression.

*T1*
Any numeric type.

*rhs*
The right-hand side expression.

*T2*
Any numeric type.

*Ret*
An Integer.

**Return Value:**

Returns the short circuit-and (conjunction) of the two operands.

**Description:**

This operator evaluates the left hand side expression. If the result is zero, then zero is immediately returned. If the result is nonzero then the right hand side is evaluated, and the logical result from that is returned.

The truth table below demonstrates all combinations of a short circuit-and operation, the '-' denotes that the operand is not evaluated.

Lhs Value | Rhs Value | Result |

0 | - | 0 |

nonzero | 0 | 0 |

nonzero | nonzero | -1 |

Short-circuiting is performed - only expressions needed to calculate the result are evaluated.

The return type is always an

The return type is always an

`KeyPgInteger Integer`, of the value`0`or`-1`, denoting false and true respectively.
This operator cannot be overloaded for user-defined types.

**Examples:**

' Using the ANDALSO operator on two numeric values

Dim As Integer numeric_value1, numeric_value2

numeric_value1 = 15

numeric_value2 = 30

'Result = -1

Print numeric_value1 ANDALSO numeric_value2

Sleep

Dim As Integer numeric_value1, numeric_value2

numeric_value1 = 15

numeric_value2 = 30

'Result = -1

Print numeric_value1 ANDALSO numeric_value2

Sleep

**Differences from QB:**

- This operator was not available in QB.
