Command: cdd
  CDD displays the name of or changes the current directory and drive.
Syntax:
  CDD [drive][path]
  CDD [..][/?]
      drive   The drive letter, e.g. C:
      path    The directory, e.g. \example\
Options:
  ..  Specifies that you want to change to the parent directory.
  -   If "last directory" feature is enabled, change to last directory.
  /?  Shows the help.
Comments:
  If drive: is specified, the current working drive is changed; this
  is the only difference with "CHDIR".
  Type CDD without parameters to display the current drive and directory.
  CDD is a command internal to command.com and needs no other file
  in order to work.
Examples:
    cdd c:\fdos     changes to the directory c:\fdos
    cdd ..          changes back from c:\fdos to c:\
    cdd \           changes back from c:\anydirectory\anysubdirectory
                    to c:\
  if you are at c:\ :
    cdd fdos        changes to the directory c:\fdos
    cdd bin         changes to the directory c:\fdos\bin
    cdd d:\example  changes the directory on d: to d:\example, AND
                    changes the drive letter to drive d:
