WorkDays was a DOS-based program I built for the Air National Guard in 1992. It was a personnel-management system that calculated pay rates and performed leave-tracking to help manage the personnel budget. Users liked it because it was fast and interactive, unlike the clunky Paradox-based applications of the day. I sold it as COTS directly to the ANG, which was an interesting experience. (Lesson learned: don't price a product so *low* that it can't be easily purchased by a federal entity!)

Wooo, check out the text-mode logo! I think I actually wrote a special program to draw this.

We even supported daisy-wheel printers! Ahhh, innocent, innocent, silly DOS.
