FMSLogo also supports a windows interface thus I/O is available through this GUI- and keyboard and mouse events can trigger interrupts. Simple GIF animations may also be produced with the GIFSAVE command. Jim Muller wrote The Great Logo Adventure, a complete Logo manual using MSWLogo as the demonstration language.
