Explanation

A Boolean declaration declares a variable of type BOOLEAN. The default initial value of a Boolean variable is FALSE.

If the := Boolean constant expression clause is specified for a Boolean identifier, this Boolean constant expression is used as the initial value for that Boolean identifier.

The values of Boolean variables are saved across a halt/load and are restored when the job restarts.
