This short Seed7 program prints a message to the console.

<<hello_world.sd7>>=
$ include "seed7_05.s7i";
const proc: main is func
  begin
    writeln("Hello World!");
  end func;

The first line includes the standard library. In contrast to other standard libraries the "seed7_05.s7i" library contains not only function declarations but also declarations of statements and operators. Additionally the "seed7_05.s7i" library defines the 'main' function as entry point for a Seed7 program.
