DENIS stands for 'Dynamic erroring and narking information system', and for a number of years was the brains behind the [[YUSU Election Nights|YUSU elections]] coverage on screen graphics until it was superceded by the higher resolution and colour depth [[Commodore Amiga]].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.
