.SH DESCRIPTION
.sp
.LP
The \fBblmaximum()\fR function replaces the contents of label \fImaximum_label\fR with the least upper bound of the labels  \fImaximum_label\fR and \fIbounding_label\fR. The least upper bound is the greater of the classifications and all of the compartments of the two labels. This is the least label that dominates both of the original labels.
.sp
.LP
The \fBblminimum()\fR function replaces the contents of label \fIminimum_label\fR with the greatest lower bound of the labels \fIminimum_label\fR and \fIbounding_label\fR. The greatest lower bound is the lower of the classifications and only the compartments that are contained in both labels. This is the greatest label that is dominated by both of the original labels.
