$DIRn$

$DIR2$ through $DIR9$ are assigned values if the DIR2 through DIR9 commands are used, respectively. Each is assigned a value after the user is prompted for a path (see the DIR2 through DIR9 commands).

Common uses include:

  • Adding the installation directory to the user's PATH.
  • Adding a device driver to the Config.sys file.
  • Providing the installation directory path to an external executable.
