hello ZE world 11

A "Hello, world" program is usually a simple computer program that outputs a message similar to "Hello, world". The text may be printed out or displayed on a screen. A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such a program is often the first written by a student of a new programming language, but it can also be used as a sanity check to ensure that the computer software intended to compile or run source code is correctly installed, and that its operator understands how to use it.
