WEll I'm half way there. I figured out how to create a File object and use the .OpenTextAsStream() to either read, write, or append (mutually exclusive but oh well).

The syntax is:

object.OpenAsTextStream([iomode, [format]]) 

iomode is read/write/append. But I'm not sure how to set the format parameter?

language ref describes the format attribute as:
Optional. One of three Tristate values used to indicate the format of the opened file. If omitted, the file is opened as ASCII.

My choices are:
TristateUseDefault - Opens the file using the system default.
TristateTrue - Opens the file as Unicode
TristateFalse - Opens the file as ASCII

Would it better to open an *.html file as UseDefault or ASCII? (server side scipt)
