The PAS file is supported on 3 operating systems. Depending on your operating system, you may need different software to handle the PAS files. Below is a summary of the number of programs that support and open the PAS file on each system platform.
What is PAS file?
The PAS file has been categorized as Developer Files. The author of this format is Niklaus Wirth. In addition to this file, the Developer Files category includes 1205 related files. Pascal Source Format appears on 3 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. The main program that supports this format is Free Pascal. This was created by Free Pascal team. Alternatively, you can use 14 other programs. You can use Oxygene, Xidicone Zeus, Embarcadero Turbo Pascal, NotePad++ text editor in case Free Pascal cannot be used.
How to open PAS file?
An often recurring problem with Pascal Source Format is that PAS is not associated with the correct program file. This is manifested by the fact that PAS files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the PAS file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Free Pascal
An often overlooked issue is to make sure that Free Pascal is installed on the computer. This can be achieved by typing Free Pascal into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open PAS files.
Programs to open PAS file
Remember to download programs supporting PAS files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Free Pascal with PAS files
However, it may happen that the application itself does not cause the PAS file to open in the Free Pascal application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the Free Pascal application as the default for handling the PAS file.
Step 3. Update Free Pascal to the latest version
If, despite the association of the Free Pascal program with the Pascal Source Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Free Pascal team website or update the program from the application.
Step 4. Check for the following problems with the PAS file
Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the PAS file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the PAS file that we want to open. However, remember that not every infected PAS file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the PAS file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair PAS file corruption. The easiest way to restore the file is from a backup or by contacting Niklaus Wirth, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file PAS except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. If possible, you can try to move the PAS file to another location.
This problem usually affects more complex files. In this case, the PAS file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file PAS to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
