You can set ZDOTDIR if you don't want the shell to set HOME (and you haven't
defined one yourself.) This is because other unix ports may expect HOME to
NOT
be set (they use their installation directory or something).

c:\windows by default. or whatever directory you installed win95.

Remember that these rules apply only if don't set HOME. Since there is
no /etc,  only the rules for locating files from $HOME are followed.

1. If ZDOTDIR is set, the shell will not set HOME. Since this may cause the
shell to crash in various places, zsh sets home to a bogus value that gives
you a clue about that went wrong, instead of crashing.

2. If ZDOTDIR is not set, and HOME is not set, then zsh sets home to the
directories
above.

the way you use a variable is a function of the shell you use. since you are
using
zsh, you use the zsh syntax. it has absolutely nothing to do with what
operating
system you are running.

you can:
1. read the README
2. read the changelog
3. email me.
4. read the source 

I know there should be more comprehensive documentation of the quirks in
this version, but i
just haven't gotten around to it. sorry.
