A "Hello, World!"program is usually a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!".A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.

The "Hello, World!" program is used to illustrate a language's basic syntax. The syntax of the language BASIC (1964) was intentionally limited to make the language easy to learn. [6] For example, variables are not declared before being used. [7] Also, variables are automatically initialized to zero. [7]
This program contains the class HELLO_WORLD. The constructor (create routine) for the class, named make , invokes the print system library routine to write a "Hello, world!" message to the output.

The program prints "hello, world" to the standard output, which is usually a terminal or screen display. The original version was: [36]
