Stands for DeltaSystems Integrated Environment. "Originally created out of a need for more flexible color ANSI, we also wanted to have a BBS that ran in the background on DOS 5.0. The software was able to run both in the foreground, and as a TSR in the background, and played MOD music files in the background. We never charged money for it, just gave it to friends who asked for it. Full featured, with split-screen chat, and an ANSI "graffiti" message of the day type system." - Charles Ying
