TREX is written in the C programming language and follows ANSI C99 conventions. Only model source code and makefiles are distributed.  The model code has been compiled and simulations executed on several computing platforms (Windows, linux) with different processors (Intel x86, AMD, Itanium2) to ensure a degree of portability. 

A TREX executable (binary) can be easily created using a C compiler in a development environment such as Microsoft Visual Studio .Net on a PC running the Windows OS. For other platforms, TREX can be compiled using a unix/linux make utility.

Notice: TREX is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
