Starts execution of the rules. If the optional first argument is positive, execution will cease after the specified number of rule firings or when the agenda contains no rule activations. If there are no arguments or the first argument is a negative integer, execution will cease when the agenda contains no rule activations. If the focus stack is empty, then the MAIN module is automatically becomes the current focus. The run command has no additional effect if evaluated while rules are executing. Note that the number of rules fired and timing information is no longer printed after the completion of the run command unless the statistics item is being watched (see section 13.2). If the rules item is being watched, then an informational message will be printed each time a rule is fired. This function has no return value.
