AND
The AND
operator
is the logical intersection operator.
Syntax
bool-expr AND bool-expr
- bool-expr is a boolean expression.
Usage
If one of the operands is NULL
, the logical expression evaluates to
FALSE
.
By default, the runtime system evaluates both operands on the left and right side of the
AND
keyword. This is the traditional behavior of the Genero language, but in fact
the right operand does not need to be evaluated if the first operand evaluates to
FALSE
. This method is called short-circuit evaluation, and can be enabled by
adding the OPTIONS SHORT
CIRCUIT
clause at the beginning of the module.
Example
MAIN
IF 256!=257 AND 257==257 THEN
DISPLAY "This line should display"
END IF
END MAIN
