PUSHD - Save the disk drive and directory

 Purpose:    Save the current disk drive and directory, optionally 
             changing to a new drive and directory. 
             
 Format:     PUSHD [path ] 
             
             path :  The name of the new default drive and directory. 
 

 See also:  CD, CDD, DIRS, POPD, and Directory Navigation. 

 Usage 

 PUSHD saves the current drive and directory on a "last in, first out" 
 directory stack.  The POPD command returns to the last drive and 
 directory that was saved by PUSHD.  You can use these commands together 
 to change directories, perform some work, and return to the starting 
 drive and directory.  The DIRS command displays the contents of the 
 directory stack. 

 To save the current drive and directory, without changing directories, 
 use the PUSHD command by itself, with no path. 

 If a path is specified as part of the PUSHD command, the current drive 
 and directory are saved and PUSHD changes to the specified drive and 
 directory.  If the path includes a drive letter, PUSHD changes to the 
 specified directory on the new drive without changing the current 
 directory on the original drive. 

 This example saves the current directory and changes to C:\WORDP\MEMOS, 
 then returns to the original directory: 

 
         [c:\] pushd \wordp\memos
         [c:\wordp\memos] popd
         [c:\]
 

 When you use PUSHD to change to a directory on an HPFS drive, you must 
 quote the path name if it contains whitespace or special characters.  See 
 File Names for additional details. 

 PUSHD can also change to a network drive and directory specified with a 
 UNC name (see File Systems for a description of UNC names). 

 If PUSHD cannot change to the directory you have specified it will 
 attempt to search the CDPATH and the extended directory search database. 
  You can also use wildcards in the path to force an extended directory 
 search.  See the Directory Navigation section for complete details on 
 these and other directory navigation features. 

 Directory changes made with PUSHD are also recorded in the directory 
 history list and can be displayed in the directory history window. 

 The directory stack can hold up to 511 characters, or about 20 to 40 
 entries (depending on the length of the names).  If you exceed this 
 limit, the oldest entry is removed before adding a new entry. 

 The /N option available in CD and CDD to disable extended directory 
 searches is not available in PUSHD.  To disable extended searches when 
 using PUSHD, save the current directory with PUSHD (without parameters) 
 and then use CDD /N to change directories, for example: 

 
      pushd
      cdd /n testdir
