chaining text : what the smater way ?

here his the complete test code ( I wont post full code) it's not intersting for the question ( this is the code i use to test)

var aaaa : String = "aaaaa aaaa   a  a  aaaa a  a a a a  aa a   aa a  a a  aaaaa    aaa   aaaa a  aa  aa  aa   aaaaaa  aaaaaaa  aaaaaa  a aa   aa  aaa  aaaa aaaaa aaaaaaa aaaaaaaa aaaaaaaaa  aaaaaaaaaa aaaaaaaaaaa aaaaaaaaa aaa aaa aaaa aaa aaaa aaaa aaaa  "

var txtCour:TextFormat = new TextFormat();

txtCour.size = 14

txtCour.font = "Trebuchet MS"

txtCour.kerning = true

var contrPt : Number = -1

var inc : Number = 1

var TtA : TextField = new TextField() ; TtA.wordWrap = true ; TtA.multiline = true;

var TtB : TextField = new TextField() ; TtB.wordWrap = true ; TtB.multiline = true;

TtA.defaultTextFormat = txtCour

TtB.defaultTextFormat = txtCour

TtA.text = aaaa

TtA.x = 132; TtA.y = 10

    TtA.width = 100 ;TtA.height = 100

    addChild ( TtA)

while (contrPt<0){

    contrPt  = TtA.getCharIndexAtPoint(TtA.width - inc, TtA.height -5)

    inc ++}

    mystB = mystA.substring(contrPt,0x7fffffff ) // cutting the string :

    TtB.text = mystB // put the end of the text in the second textfield

    addChild ( TtB)

//====================================================

The purpose of this is make a page layout that goes like this  ( the begining of the text is in the fist text field and the rest in the second text field:

ImageImageImageImageImageImageImage      FistTexfieldFistTexfieldFistTexfieldFistTexfield

secondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextField

secondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextField

secondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextField

secondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextFieldsecondTextField

Usualy people use html text to do this kind of things. In my case it's not possible
