Dear JavaScripters:

     In each case, the code is the in the head of the page.

     I can code

var Output;
Output=alert;
Output("This is the output.");

and see the expected alert box.

    I can code

var Output;
Output=document.write;
Output("This is the output.");

but I do not get the output.  I get an error of "Error: Invalid
calling object".

    I can code

var Output;
Output=document;
Output.write("This is the output.");

and see an output line in the body.

     Why is the second example above wrong?  I am using IE 9 on
Windows 7.

Sincerely,

Gene Wirchenko
