An welchem Datum war Ostern in den vergangenen Jahren?

year := random(1000)+1900;
writeln('In year '+intToStr(year)+' was eastern sunday on '+EasterSunday(year));

Fibonacci

function fib(n: integer): integer;
  var tmp: integer;
  begin
    if n=1 then result := 1
    else if n=2 then result := 1
    else begin
      tmp := fib(n-1);
      result := tmp + fib(n-2);
    end;
  end;

writeln(intToStr(fib(8)));

Canvas Example

var i:integer;
    j:integer;

selectCanvas(1);
canvas_clear();
for i:=0 to 5 do begin    
 for j:= 0 to 5 do begin
  canvas_setColor((255-42*i),(255-42*j),0);      
  canvas_fillRect(j*25,i*25,25,25);           
  
  canvas_setColor(0,0,0);      
  canvas_text(j*25+7,i*25+16,'x',16);    
 end;
end;

Turtle Example

var isUp:Boolean;

selectCanvas(2);
canvas_clear(); // Zeichenfläche löschen
turtle_move(200,100); // Turtle in die Mitte stellen

isUp := false;

for i := 0 to 17 do begin
 turtle_penColor(i*10+50,0,250-10*i);  
 turtle_penWidth(10);
 turtle_forward(20);  
 turtle_right(20); 
 isUp := not isUp; 
 if isUp then turtle_penUp() else turtle_penDown();
end;

var Bob:Integer;
    Eva:Integer;
    step:Integer;

selectCanvas(3);
Bob := createTurtle(3);
Eva := createTurtle(3);

canvas_clear(); // Zeichenfläche löschen

selectTurtle(Bob);
turtle_penColor(255,0,0);
turtle_move(300,200); 

selectTurtle(Eva);
turtle_penColor(0,255,0);
turtle_move(50,50);

for step := 0 to 500 do begin 
 // Bewegung von Eva
 selectTurtle(Eva);
 turtle_setAngleTo(Bob);
 turtle_forward(2);

 // Bewegung von Bob
 selectTurtle(Bob);
 turtle_forward(random(8));
  if step mod 2 = 0 then
    turtle_right(random(90))
  else
    turtle_left(random(90));

end;

Sound Example

selectSound(1); // Piano MIDI 
for i := 0 to 10 do 
 sound_play(50+i*2,100);

var Lied:String;
    key:integer;
    dauer:integer;
    c:Char; k:Char;

Lied := 'E-4 E-4 E-2 E-4 E-4 E-2 E-4 G-4 C-4 '+
        'D-4 E-1 F-4 F-4 F-4 F-4 F-4 E-4 E-4 '+
        'E-8 E-8 E-4 D-4 D-4 E-4 D-2 G-2';

selectSound(19); // 19. MIDI organ

for i := 1 to length(Lied) do begin
 if i mod 4 = 1 then begin
  c := Lied[i];
  k := Lied[i+2];
  if c = 'C' then key := 60;
  if c = 'D' then key := 62;
  if c = 'E' then key := 64;
  if c = 'F' then key := 65;
  if c = 'G' then key := 67;
  if c = 'A' then key := 69;
  if c = 'H' then key := 71;
  if k = '1' then dauer := 1000 div 1;
  if k = '2' then dauer := 1000 div 2;
  if k = '4' then dauer := 1000 div 4;
  if k = '8' then dauer := 1000 div 8;

  sound_play(key,dauer);
 end;
end;

eingabe := inputDialog('Gib deinen Namen ein:');
 showMessage('Hallo '+eingabe+'!');
