a bit of the recursive function for paging. caution, this is not the full code.

gistfile1.as

function generatePaging(fetchSize:Number=128):void
{
	var buffer:Array = new Array();
	var i:Number = 0;

	while (i < fetchSize && wordIndex + i < textArray.length)
	{
		var word:String = textArray[wordIndex + i];
		buffer.push(word);
		i++;
	}
	
	var bufferToBePushed:String = buffer.join(" ");
	var wordsToBeWritten:String =  pageArray[pageIndex] == null ?  bufferToBePushed : pageArray[pageIndex]  + " " + bufferToBePushed;
	textContent.htmlText = wordsToBeWritten;
	if (textContent.textHeight > textContent.height - 20)
	{
		fetchSize = fetchSize / 4;
		if (buffer.length == 1)
		{
			pageArray[pageIndex] = wordsToBeWritten;
			wordIndex = wordIndex + i;
			pageIndex++;
			return;
		}
		else
		{
			generatePaging(fetchSize);
		}
	}
	else
	{
		pageArray[pageIndex] = wordsToBeWritten;
		wordIndex = wordIndex + i;
		generatePaging(fetchSize);
	}
}
