Buat aplikasi baru
Tempatkan sebuah edit dan dua buah tombol, isi edit dengan nilai nol, ganti caption tombol masing-masing “Jalan” dan “Stop”
Buat variabel global “jalan” berjenis boolean
Dobelklik tombol “Jalan”, ketikkan perintah sebagai berikut
jalan:=true;
x:=strtoint(edit1.Text);
while jalan=true do begin
x:=x+1;
edit1.Text:=inttostr(x);
application.ProcessMessages;
sleep(1000);
end;
(jangan lupa membuat variabel lokal “x” berjenis integer sebelum begin)
Dobelklik tombol “Stop”, ketikkan perintah sebagai berikut
jalan:=false
jalankan program. Jika gagal, ubah deklarasi x dari x:int; menjadi x:integer;
