In this case, the parameter `"a number"` in the ONELAB database and the local variable `n` are both assigned the argument value, here `2.718`. All subsequent `n = DefineNumber[ xx , Name "a number"]` statements will have the same behavior, as long as the attribute `ReadOnly' of the parameter `"a number"` is not reverted to 0. Logically, `ReadOnly` parameters are not editable in the graphical user interface.

A `/` character in a parameter name results in the creation of a sub-tree in the hierarchical parameter tree displayed in the graphical user interface. See also below for all the optional attributes that can be specified in addition to the `Name` of the parameter.
