See figureIt provides hypertext-like facilities in picture form, enabling the user to navigate through a development through a push-button interface.
The following options are initially presented:
The last option provides a sub-menu of all constructs that may currently be browsed (i.e. all specifications, refinements and implementations that are currently analysed), with subsequent selection resulting in a detailed overview of the selected construct.The specification and design overviews are presented in a layered horizontal manner; selecting any construct will result in a detailed overview of that construct, when the diagram is displayed in vertical form, with seen/ used constructs (if any) to the left of the overviewed construct and included constructs (when overviewing a specification) or imported constructs (when overviewing a design) on the right:
Selecting any of the constructs will result in an overview of that construct.
Subsequently electing the main (highlighted) construct will then popup a selection comprising the abstractions /refinements of that construct (if any); subsequent selection will result in an overview of that construct; the selection also provides the facility to open the main construct for hypertext viewing.
Each overview provides the following options:
restores the previous overview (where applicable).
provides an overview of the specification construction.
provides an overview of the design.
