TradeWars 2002 Assistant (TWASSIST)

Every good trader needs an assistant.  The assistant keeps records and
  provides information so the trader can make better decisions.  Trade Wars
  2002 (TW2002) is a bulletin board door game by Martech Software, Inc.  The
  game has a lot of different aspects and keeping track of all the details by
  hand can be quite tough.  I looked at utilities to help me with the game
  but could not find one that met my needs or the needs of my friends, so I
  decided to build one from scratch.  Trade Wars 2002 Assistant (TWASSIST)
  was born.  After nine months of continuous work (with only a few sanity
  breaks) version 1.0 was ready and released on October 12th, 1992.  Version
  2.3 was released on December 2, 1995.
