autoit - 値ごとにスクリプトを繰り返し入力せずにジョブを繰り返します

Question

この Autoit スクリプトはうまく機能していますが、値ごとにスクリプトを繰り返し入力せずにジョブを繰り返すにはどうすればよいですか?

Value1 = usernameA passwordA と連動

Value2 = usernameB は passwordB で動作します

Value3 = usernameC は passwordB と連動します

#include <IE.au3>
$oIE = _IECreate ("www.site.com/login")

$username = _IEGetObjByName ($oIE, "q_username")
$id = _IEGetObjByName ($oIE, "q_username")
$password = _IEGetObjByName ($oIE, "q_password")
$id = _IEGetObjByName ($oIE, "q_password")
$button1 =  _IEGetObjByName ($oIE, "login")

_IEPropertySet($username, 'innerText', 'usernameA')
_IEPropertySet($id, 'innerText', 'usernameA')
_IEPropertySet($Password, 'innerText', 'passwordA')
_IEPropertySet($id, 'innerText', 'passwordA')
_IEAction ($button1,"click")

こうなってほしくない！

#include <IE.au3>

$oIE = _IECreate ("www.site.com/login")
$username = _IEGetObjByName ($oIE, "q_username")
$id = _IEGetObjByName ($oIE, "q_username")
$password = _IEGetObjByName ($oIE, "q_password")
$id = _IEGetObjByName ($oIE, "q_password")
$button1 =  _IEGetObjByName ($oIE, "login")

_IEPropertySet($username, 'innerText', 'usernamea')
_IEPropertySet($id, 'innerText', 'usernameA')
_IEPropertySet($Password, 'innerText', 'passworA')
_IEPropertySet($id, 'innerText', 'passwordA')
_IEAction ($button1,"click")

$oIE = _IECreate ("www.site.com/login")
$username = _IEGetObjByName ($oIE, "q_username")
$id = _IEGetObjByName ($oIE, "q_username")
$password = _IEGetObjByName ($oIE, "q_password")
$id = _IEGetObjByName ($oIE, "q_password")
$button1 =  _IEGetObjByName ($oIE, "login")

_IEPropertySet($username, 'innerText', 'usernameB')
_IEPropertySet($id, 'innerText', 'usernameB')
_IEPropertySet($Password, 'innerText', 'passwordB')
_IEPropertySet($id, 'innerText', 'passwordB')
_IEAction ($button1,"click")

$oIE = _IECreate ("www.site.com/login")
$username = _IEGetObjByName ($oIE, "q_username")
$id = _IEGetObjByName ($oIE, "j_username")
$password = _IEGetObjByName ($oIE, "q_password")
$id = _IEGetObjByName ($oIE, "q_password")
$button1 =  _IEGetObjByName ($oIE, "login")

_IEPropertySet($username, 'innerText', 'usernameC')
_IEPropertySet($id, 'innerText', 'usernameC')
_IEPropertySet($Password, 'innerText', 'passwordC')
_IEPropertySet($id, 'innerText', 'passwordC')
_IEAction ($button1,"click")

また、終了時にスクリプトの最初の行に戻るにはどうすればよいですか?
