Hello, World!

Although QED is a programming language with a compiler, it may act as a scripting language as shown in the various demos below. Of course, we’ll start with the traditional “Hello, World!” to assess the language simplicity. It is a two-liner but you may try out this code with only one of the two lines, depending of what you want. Click Run to execute it.

The first line is a console version of the application, whereas the second line is a GUI version (both versions can coexist). The GUI version is shown on top-right section and the console version is output at bottom-right.

I know I’m already digressing here with some GUI code but don’t worry, we won’t see more of it in this section. I just wanted to show you a quick glimpse of QED output possibilities because, well, this is the venerable “Hello, World!” app and it had to showcase both output media.
