===== How to create an Hello-World-Application =====

The well known 'Hello-World'-application is quite easy to implement. The command you need to use is the ''[[gsys:command:print]]'' command. After it you have to add your text you want to print. As a developer you call this a "string", because you have a string of characters. A string starts and ends with quote signs. So if you want to make 'Hello World!' to an string you have to type:
<code>"Hello World"</code>

Now you have to say Genesys that it has to be printed on your console. Therefor you use the ''[[gsys:command:print]]'' command and put the string behind.
As in most programming languages a command is complete if a semicolon is following.

<code>print "Hello World!";</code>

That's it. ''[[gsys:command:print]]'' is an internal command, you do not need to include something, you do not need make a class or a function around it. As soon as Genesys has found an instruction it will create a function and a class around it by itself.

Put that line into a text editor of your choice and save it as 'helloworld.g'. Now call the Genesys-compiler to interprete it:

<code>$ gsys -r helloworld.h

Hello World!
</code>

Well done!
