Array access notation with strings?

Question

I may be confused, but I thought you could use array access
notation with strings. Can someone tell me why this code doesn't
work (or suggest new code):
the code is meant to rewrite the block of text in tText at a
rate of one character per frame... (when the function is called
once per frame) but it doesn't work.

It's made for objects, actually. The array access operator,
[], allows
you to access elements from an Array instance and also lets
you access
properties from any sort of object. The "trick" it provides,
in this latter
case, is that you can refer to these properties -- within the
brackets --
with strings, so it's often used to reference objects
dynamically.
> var sWorkingText:String = tText.text;
Here you've declared a String variable and set it to the
TextField.text
property of some textfield. So far, so good.
> var sNewText:String = oPhotoText[sPageFocus];
Here, you've declared a String variable, but it seems that
you're
setting it to a property of the oPhotoText object. That's now
how this
works.
The array access operator allows you to *use* strings to get
at an
object's properties:
// functionally equivalent
someObject.property1
someObject["property" + 1];
var x:Number = 1;
someObject["property" + x];
Does that help?
