Basic Source Code Format | N/A | Developer Files |
The .BAS file extension is used for a BASIC source code file. This type of file is applicable to several different dialects of BASIC, including Microsoft Visual Basic, GWS BASIC, and Windows PowerShell. Files with this file extension contain programming commands written in BASIC language, and can be used to allow easy manipulation of an external object such as a text file or video. As an example, a BASIC source code file can be used to create a program that shifts the colors of an animation when the program is next run.
Technical Details
BAS files are typically written in an ASCII (American Standard Code for Information Interchange) format, meaning that the file uses standard characters to encode its text content. This code is plain-text based and editable using any text editor software that supports the ASCII code set. The text itself contains functions, methods, keywords, and other language-specific elements, which are understood by any software interpreting the language that the file was written in.
Other similar source code file extensions include .C, .CPP, .HPP, .XPP, and .F90, which represent various specific programming languages such as C++, C#, and Fortran.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BAS) 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 .BAS 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 .BAS 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 .BAS 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 .BAS extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BAS file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BAS 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 .BAS file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BAS file) will be extended to the maximum.
It is also good to check
- if the .BAS file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
