Rexx - Brexx

BRexx is a lighter weight implementation of Rexx. It still has a lot of functionality to offer as part of the Rexx implementation.

Setting up BRexx

The first step in BRexx is to set it up on the local machine. To do this, one needs to perform the following steps −

Step 1 − Go to the BRexx download site − https://ftp.gwdg.de/pub/languages/rexx/brexx/html/rx.html

Go to the downloads section and download the product.

Step 2 − Unzip the contents of the Brexx zipped file.

Step 3 − Add the BRexx\bin path to the path variable on the system.

Step 4 − Create a new variable called RXLIB and point it to the lib folder in the Brexx folder.

Running the First BRexx Program

Create a file called main.rexx and place the following code in the file.

/* Main program */ 
say ‘hello’ 

To run the program, run the following command.

rexx32 main.rexx 

When you run the above command, you will get the following output.
