Does anybody know how to do something like:

document = new Object();
document.x = 5;
x = document.x;
.
.
.
such that when the value of document.x changes, the
variable x will get updated w/ the new value.

The way it's written above, x will not get updated
automatically when i change the value of document.x
after the assignment of x = document.x.

Thanks,
Tom

Hmmm, sounds like x/y=t*u-4+33=x+y*u/t  ;-)

Sorry, just having some very late night fun at your expense!

Anyway, I am assuming you are referring to something like this...
<xmp>
// in a form, for example
var x="500";
if(document.myObj.value != x)
    document.myObj.value = x;
</xmp>
Yes/no?

I think that variable x has its own location for the value like this, say:

_x  dd  ?                        ;internal variable
x    dd  OFFSET _x       ;pointer

when you do

                                   x = document.x

this should mean you copy the value of document.x into internal _x, so that
you have two copies of the value of document.x.
MK.

OK, I've not been precise. I have another suggestions.
Variable x is also the object variable, but when you use it the first time
via assigning the value of predefined objects like String or Number the
proper constructor is invoked. You can not create C pointers on such
objects.
