Notes about the TRU file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The TRU file type is primarily associated with 'True BASIC' by True Basic Inc.. John G. Kemeny and Thomas E. Kurtz invented BASIC for use at Dartmouth College. They made it freely available to everyone who wanted to learn how to program computers. It soon became a world standard. In 1983 they created True BASIC to incorporate and showcase all the advanced developments they had added to their language, and offered it as a commercial product.
