On a Windows system, the path:
D:\
is known as the HOMEPATH.

----
[LV] Can anyone explain how Tcl makes use of this?  What does HOMEPATH
mean? - [RS] is not sure, but this page was prepared to live from [Tcl syntax help].

----

On my windows box my HOMEPATH is:
 
 \Documents and Settings\jrankin

I'm not sure why it would ever be the root of d, unless it has been explicitly set that way.
Given the location of this path, perhaps it refers to the Windows equivalent of the user's home directory? - [WJR]

[ZLM]:

   C:\>set HOME
   HOMEDRIVE=P:
   HOMEPATH=\
   HOMESHARE=\\acefpscpd001\PSI0005JLM$
   C:\>p:
   P:\>
   P:\>cd %HOMEPATH%
   P:\>
   P:\>c:
   C:\>
   C:\>cd %HOMEPATH%  
   C:\>

[BR] 2003-10-28: On my system (W2K) I see this:

  c:\> set HOME
  HOMEDRIVE=C:
  HOMEPATH=\Documents and Settings\benny

I always interpreted this as that MS wanted something like $[HOME] on Unix but
in two pieces so that you can use it in batch files like

  %HOMEDRIVE%
  cd %HOMEPATH%

Note for those not familiar with Windows command/batch language: On Windows,
plain '''CD''' doesn't change the drive.  You do that by just giving the drive
name, as the first line in the code example does.

Tcl seems to think the same, it synthesizes a [HOME] variable for me from those
bits, if I don't have one:

  c:\> set HOME
  HOMEDRIVE=C:
  HOMEPATH=\Documents and Settings\benny

  c:\> tclsh
  % set env(HOME)
  C:\Documents and Settings\benny
