- What is an AUX?
  - An AUX is a named reference to a directory, like a symbolic link in Unix.
  - NeXtMidas has an `AUX` table containing the list of AUXes.
    - An AUX name can be any legitimate table name.
    - An AUX can be a traditional directory name or a URL.
  - Special Convention: An AUX path can be defined with a plus sign taking the place of the user name.
    - Example: `/midas/data1/+/` would become `/midas/data1/smith/` for a user `smith`.
    - This allows a common AUX configuration to be used for various users who each have independent data directories.
- Define an AUX entry:
  - An AUX entry is added by setting an entry in the AUX table using SET or RESULTS.

        nM> set aux.mydata "/home/student/mydata/"
        nM> results aux.moredata "/home/student/anotherarea/"

X-Midas Users Take Note:
In X-Midas, all AUX entries must be identified by a number. NeXtMidas allows the use of names for the AUX entries.
