Re: define Info's "dir"?

The solution I was looking for has nothing to do with Info.  

When I do "C-x f" to visit a file, I am prompted to enter the name of 
the file.  In the prompt (in the minibuffer) is the default-directory 
already specified for me.  This default-directory, however, is the one 
for the current buffer.  Instead, I would like a command which overrides 
the default-directory for the current buffer when I do "C-x f" to visit 
a file,

To explain the same thing another way....  When I do "M-x cd" I'm 
prompted for the default-directory.  But this sets this variable for the 
current buffer only.  I would like to do, say "M-x gcd", and enter the 
name of a directory which would set, say, global-default-directory which 
would persist for the entire emacs sesssion or until I change it to 
something else.  Then, no matter what is the current buffer's 
default-directory, if I do "C-x f" to visit a file, the prompt will 
specify the global-default-directory.

So you see, it has nothing to do with Info.
