TR4W is now Open Source



The TR4W support group is pleased to announce that TR4W is now Open Source’d on GitHub and licensed under GPL V3.

TR4W (TRlog 4 Windows) is an amalgam of base TRLOG code (TR4W/SRC/TRDOS) -originally authored and Copyrighted by N6TR, with a Windows application layer (TR4W/SRC) -originally authored and Copyrighted by UA4WLI. TR4W is mostly 3GL with some critical code in assembler. As such it is built for speed and supports over 150 contests.

The code is written in Object Pascal and can be compiled using Delphi 7 compiler, which you can google.
