The Pro/3 main (MDI) window has a menu-bar, a tool-bar, a status/message bar and a windowing area . The Assistant Window is a permanent fixture of the MDI window.
Status/message bar (at the bottom of the MDI window) typically shows the type of processing currently being done by Pro/3 (normally ended by ...). It also shows processing just completed.

Tool-bar provides icon-shortcuts (tools) to selected entries in the menus and also some status displays (in most cases associated with tool(s) just right of the display. Each tool's corresponding menu item is displayed in the Messsage-bar on "mouse-over". The status displays are:

  • Current trace level (left of the  T++  tool which is used to change trace level0.

  • Status of caches:  T : terminology cache active,  S : sentence model cache active (left of the corresponding to cache ON/OFF toggles).

  • Status of flags:  E : error-flag ON,  Q   :quit requested,   !  :KB not fully dervided   + : KB has been changed (left of the flag reset tool  X ).
