.TPU File Extension
What is a TPU file?
A TPU file is a Turbo Pascal unit. It contains a compiled program module that Turbo Pascal developers can import into a Turbo Pascal program, via the uses keyword. Saving a module as a TPU file allows developers to reuse the functions and procedures that module contains in multiple programs.
Turbo Pascal is a development kit for the Pascal programming language. It includes an IDE and a compiler that allow developers to develop, compile, and run Pascal programs.
Versions 4 and later of Turbo Pascal allow developers to compile program modules into TPU files. Typically, these modules contain common functions and procedures that a developer wants to include in multiple programs. Storing these functions and procedures in a single TPU file, rather than rewriting them in each program, makes maintaining and troubleshooting them easier.
Each TPU file is built from a corresponding .PAS file. These PAS files start with the unit keyword; they are typically named similarly to their TPU counterparts.
NOTE: Different versions of Turbo Pascal use differently-formatted TPU files. Therefore, TPU files created using one version of Turbo Pascal may not function correctly in other versions.
How to open a TPU file
TPU files are not meant to be opened. To edit the code a TPU file contains, edit and recompile the corresponding PAS file.
