FirstMate was originally written in 1989-1996 for DOS, and later converted to Windows in 2001. Although I did some closed beta testing, the helper never made it to a wide release and all source code was lost in 2003 when I was fired from my job at the time.
2011 - With the release of the 25th Anniversary Edition of TWGS, I have decided to port FirstMate to C#/WPF. The new version will use the .net CodeDom runtime compiler for the scripting engine, which will allow traders to write scripts in any .net language.
