REWIND - do label searches from start of command file.

$*$ReWind $*$ReWind ON: tells EXEC to go back to the beginning of the command file every time it starts searching for a label (because of a $*$GOto directive).
$*$ReWind OFF: tells EXEC to start searching for a label at the $*$GOto directive that jumps to the label. This is the default when EXEC starts executing.
