The PAS file extension is created by the Delphi Pascal programming language, which was developed by Borland. The PAS file is a plain text source code file which contains Pascal programming language code. It contains the instructions which can be accessed and compiled by a Delphi compiler, such as earlier versions of the Turbo Pascal compiler. Usually, the Pascal programming language is used to create programs for small-scale tasks due to its simple syntax, while the larger-scale applications are created using other languages like C++ or Visual Basic.
Similar File Extensions
The most similar file extensions used with the Pascal programming language are .DPR, .DFM, .DPK, and .INC. The first three file extensions are more technical than the last one – they are related to the Pascal development environment managed by Delphi. The .INC file stores macros and include codes and acts as an import/export mechanism between Pascal projects. Thus, programming languages requiring logical reasoning (such as Pascal) often use these files for faster compilation.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PAS) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .PAS extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .PAS file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .PAS extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .PAS extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PAS file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .PAS file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .PAS file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PAS file) will be extended to the maximum.
It is also good to check
- if the .PAS file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
