ok, let me be as precise i can.
1. zsh first checks for the existence of the ZDOTDIR variable. If that is
it checks for HOME.
2. if neither is set it, it sets a HOME variable.
This is os-dependent, as outlined in the README.
Once this value (ZDOTDIR or HOME) is determined, the win32 version itself
have it's own search mechanisms for any .rc files. It is only trying to
pick a good default SINGLE directory to look for startup files.
what that means is that after this point, the shell behaves as if it was
a unix system with no global /etc directory or other locations to check for
startup files. So, you only have the user's $home to look at.
If this still does not make sense, i'm afraid you will have to hope for
someone more eloquent to explain it.

If you installed in c:\win95 and c:\nt, then each is
your "windows directory" when you boot into the specific OS.
Again, there is no "first" or "second" directory to be searched. It's either
your ZDOTDIR, or a HOME directory set by you or the shell.
this WILL be different between the two OSes if you let the shell pick the
default place. In the case of a multiboot, you therefore need to set HOME
explicitly in at least one of the OSes, if you want a common startup file.
Or you can put dummy .zshrcs that all source a common one in each
thus, if you have win95 in c:\windows and nt4.0 in c:\nt40, put
a .zshrc with
in each c:\windows, and another similar one in
c:\nt40\profiles\<your user name>

why in god's name would the shell search your disk for a .zshrc ?
it assumes a HOME directory name and sees if you have .zshrc
there. if not, it starts without one.

If you had used nt for any length of time, you would know that these are set
Also, the $ notation is used in the readme because it's familiar unix
if you are trying to create a SOMEVAR path variable from variables FOO and
you would use
%FOO%\%BAR% in a batch/cmd file
$FOO/$BAR in a zsh/tcsh script.

It seems to me that you are trying to figure out how to use
zsh without actually using it on NT. please try it first and then
email me (directly at amold@xxxxxxxxxxxxx) with any
questions. There are dozens of people already using the
shell, and i've *never* had questions like this.

when i have some more time, i will try to put that together.
