The AND function performs a logical conjunction between its parameters, returning true or false based on this conjunction. Each of its parameters is evaluated in the order provided as Boolean values. If any parameter is evaluated as false, the return value is false. Otherwise the function returns true. The function must have at least one parameter and may contain as many more as is needed.
| @AND (Expression 1 [, ..., Expression N]) | |
|---|---|
Expression 1 | Required Boolean parameter, the first to be evaluated by the
function. If false, evaluation stops and the function returns false.
If true, the function will return true if no other parameters are
provided or evaluate the next parameter. |
Expression N | Optional Boolean parameters, each evaluated by the function
in the order provided. Evaluation stops for the first false value
found and the function returns false. Otherwise the function returns
true. |
