Open REXX File

REXX is an interpreted programming language developed by IBM. It allows for writing scripts and macros, primarily used for task automation on systems running OS/2 Warp, Windows, Linux, Unix, and mainframe operating systems. The scripts are stored in files with the .REXX file extension.

Understanding the REXX File Extension

In its most common usage, the REXX file extension is associated with the Restructured Extended Executor (REXX) language script files. Such files typically contain scripts or macros written in the REXX language, which are then interpreted and run by a REXX-compatible interpreter. These interpreters can either be built into the operating system or available as standalone tools.

More about REXX file format can be found at IBM's official documentation.

How to Open REXX Files

To open and use files with a .REXX extension, you usually need a REXX interpreter. Below are few interpreters available for different platforms:

Regina REXX interpreter - A free, open-source REXX interpreter that runs on most Unix platforms, Windows, and OS/2.
Open Object REXX (ooRexx) - An open-source REXX interpreter that introduces object-oriented extensions to the REXX language. Compatible with Windows, Linux, Mac OS X, and various Unix platforms.

Editing REXX Files

REXX files are essentially text files and can be opened and edited with any text editor. However, text editors specialized for coding, like Emacs, Vim, or Visual Studio Code, provide syntax highlighting and other useful features when writing and debugging REXX scripts.

Executing REXX Files

To execute a .REXX file, provide it as an argument to the REXX interpreter as per interpreter's instructions.

For example, if you use Regina REXX, you might execute your script by typing the following command in the command prompt: rexx my_script.rexx.

Note that some operating systems may require additional setup to recognize .rexx files automatically.

REXX File Important Information

REXX file extension is quite unique and it's unlikely that it would be associated with different types of content. However, if you have a file with .rexx extension and have trouble opening it, consider researching the file's source further. As always, proceed with caution when opening files of unknown origin.

It's good to understand that working with the REXX file extension and automated scripts in general requires some knowledge about programming, so beginners might find it a bit challenging. Nevertheless, REXX is known for being a high-level and easy-to-learn language, which makes it suitable even for beginners who wish to automate processes on their systems.

How Can I Open REXX File on Windows

We researched and learned that the best way to open REXX file is to find a REXX file in question in Windows OS File Explorer and double click on it to launch the corresponding application.
If a REXX file is not opened in an application and you instead get a "Windows can't open a file" error message you should try looking for an application which can open the file in question.
If you know the application which can open REXX file then run it and see if there is a File->Open main menu option in the application.

How Can I Open REXX File on Mac OS

We recommend to find a REXX file in question in Mac OS Finder and double click on it to launch the corresponding application.
If a REXX file is not opened in a Mac OS application and you instead get a "There is no application set to open the file" error message you can click on "Search App Store" in the error dialog and Mac OS will show you applications compatible with REXX file.
If you know the Mac OS application which can work as REXX file opener you can choose the "Choose Application..." option in the error box to associate the file extension and open REXX file in it.
If you don't know the application which can open REXX file then try to search for "REXX viewer", "application to open REXX file" or "read REXX file" queries in the online search engine you like.
Install the application you found and check if it can read REXX file

How Can I Open REXX File on Android

If you downloaded a REXX file on Android device you can open it by following steps below:

In the Android apps list on your Android device find "My Files" or "File manager" app and tap to start it.
Tap on "Downloads" folder inside the app.
You should see your downloaded REXX file in that folder.
Tap on the file. If Android device supports opening the file you downloaded it will open in the corresponding app.
If file does not open you can look for the corresponding app that can open the file by searching Android App Store for the "REXX".
If you cannot open the file with the apps from Android App Store it is possible that the file could only be opened on desktop platforms such as Windows or Mac OS. Try searching for "REXX viewer", "REXX file reader" online and see if any desktop applications can open it.
It is also possible that the file you downloaded is outdated and is no longer supported.

How to Open REXX File on iPhone or iPad

To open REXX File on iOS device follow steps below:

We advies to open Files app on your iPhone or iPad device. You can find it by swiping down on the home screen and typing "Files" in the search bar.
Tap on the Downloads folder on the Files app home screen.
You will see all files that you recently downloaded. Tap on the REXX file to view it.
If you have the right app that can open it it will automatically launch and open your file.
If you don't have the app which can open it you need to serch Apple app store for "REXX". This way you can find apps which can open REXX files.
If this doesn't help it is possible that your file could be opened only by the desktop application. To find an app which can open it on desktop look for "REXX viewer" or "REXX file" online in your favorite search engine.
