=={{header|Seed7}}==

Code execution in Seed7 always starts with main. This holds for text programs:

<lang seed7>$ include "seed7_05.s7i";

const proc: main is func

begin

writeln("hello world");

end func;</lang>

And for grahical programs:

<lang seed7>$ include "seed7_05.s7i";

include "draw.s7i";

include "keybd.s7i";

const proc: main is func

begin

screen(200, 200);

KEYBOARD := GRAPH_KEYBOARD;

ignore(getc(KEYBOARD));

end func;</lang>
