The console window used for the windowed executable is based on code
written by Jan Wielemaker <jan@swi.psy.uva.nl>.
In SICStus 3.8 the console was enhanced with menu access to common
Prolog flags and file operations. Most of these should be self
explanatory. The Reconsult item in the File menu
reconsults the last file consulted with use of the File menu. It
will probably be replaced in the future with something more powerful.
Note that the menus work by simulating user input to the Prolog top level or debugger. For this reason, it is recommended that the menus only be used when SICStus is waiting for a goal at the top-level (or in a break level) or when the debugger is waiting for a command.
