TScript was written for the purpose of adding scripting abilities to traditional C++ programs. This was required for the Texas Business Software to allow uses to add installation specific functionality to the package once the software has been installed.

Within the Texas Client software, TScript is used for small changes in the functionality software from enabling the filtering of messages into separate inboxes, to major changing in the customisation for the printing processes, to enable users to control the final look'n feel of each report.

TScript has also been designed to function within the server software. This enables uses to create their own database queries and processes. This enables users to decide exactly what they're own installation does and how the software matches their own business processes.
