XPL

The XPL (eXtended Programming Language) is a scripting language used primarily within certain IBM i environments, and it’s part of the broader RPG (Report Program Generator) family. Writing “Hello World!” in XPL can be quite straightforward since XPL scripts are designed to handle various tasks on an IBM i system.

Below is a simple example of how you might write “Hello World!” using XPL:

DEFINE DATA LOCAL
1 #MSG        PICTURE X(20)
END-DEFINE

#MSG = 'Hello World!'

WRITE #MSG
END

Explanation:

• DEFINE DATA LOCAL: This section declares local data definitions.
• 1 #MSG PICTURE X(20): Declares a variable #MSG that can hold up to 20 characters. The PICTURE X(20) specifies it’s a string.
• #MSG = ‘Hello World!’: Assigns the string “Hello World!” to the variable #MSG.
• WRITE #MSG: Outputs the value of #MSG, which is “Hello World!” in this case.

This script will display the message on the standard output, typically the console or terminal where you run the script. You can execute XPL scripts using tools available in IBM i environments, such as the Job Control Language (JCL) or through an integrated development environment like Rational Developer for i.
