+//
+//  The  hint  sequence  values  are  used  as  step  values  and  can
+//  optionally  define the  minimum and  maximum value.   Intermediate
+//  values are  allowed but  the step  up/down arrows  and accelerator
+//  keys will only use the hints.
+//
+//  Ensure that the default minimum  and maximum values are sufficient
+//  to allow initial initialization if done before the hints are set.
