+The ID subcommand also pertains to boxplots.  If given, it must
+specify a variable name.   Outliers and extreme cases plotted in
+boxplots will be labelled with the case from that variable.  Numeric or
+string variables are permissible.  If the ID subcommand is not given,
+then the casenumber will be used for labelling.
 
 The CINTERVAL subcommand specifies the confidence interval to use in
 calculation of the descriptives command.  The default it 95%.
