DENIS stands for 'Dynamic erroring and narking information system', and for a number of years was the brains behind the YUSU elections coverage on screen graphics until it was superceded by the higher resolution and colour depth Commodore Amiga.
Originally conceived in 1987 by Simon Barton, it was later revised in 1994 by Chris Kwouk, and unusually for YSTV home grown software included detailed program design notes - some 50,000 characters worth.
It featured a menu driven interface which launched a number of smaller programs, mainly because any colour graphics consumed over 60% of the BBC Micro's memory leaving very little room for software to generate it. It was conceptually split into editor/display/administrator, with final output including animated bar charts and pie charts.
