Using Logical Names

  A logical name usually represents a complete or partial
  file specification, a device name, or another logical name.
  You can give frequently used files, directories, and devices
  meaningful logical names that are easier to remember and
  type than the full file specifications.

  Logical names also let you keep your programs and com-
  mand procedures independent of physical file specifications.

  Logical names can be defined by you or by the system.
  Logical names and their definitions are kept in tables called
  logical name tables.
