closing windows

[ksmloh]

I have a html page (sample1.htm) that opens a window,
a = window.open("sample2.htm","pop","");

and sample2.htm opens another window
b = window.open("sample3.htm","pop2","");

So how, from sample1.htm ,
do we close the window containing sample3.htm?

err.. we do not open them windows in the first place ..

granted b is a global variable

b.close();
