IIRC I just did a Google search for chdrive, because I don't think the
term's used in other programming languages. But, yes, if you are looking
for chdir, you'd certainly need to cut it back with vba  or excel  or
something
similar in the search too.

Google is not a language reference, it's just that you can be pretty certain
that people will already have posted information to the web that answers
your questions.
