0.   Declare `A'.
0.1. Append a semicolon to the script's first line (yes, it is an example;
     a bad one).
1.   Drop document.writeln() in favor of document.write() or methods 
     introduced with W3C DOM Level 2 (which IE/MSHTML supports from version
     5.0 on).
2.   If you use document.write(), escape at least the `<' in the generated
     script code.  If you use the new methods, nothing needs to/must be
     escaped, though.
3.   Remove the extra `"'.

Please do not post attribution novels, and get a real name.

Not with javascript. Nonsense propagates like wildfire in this field.
