Aliases are abbreviated reference names  for  long  identifiers  that
  have  been  entered  in  the  source code.  To define an alias for an
  identifier on which  the  cursor  is  currently  located,  press  the
  GOLD-CTRL/A key sequence and type the abbreviation at the prompt:

       _Alias name: name

  Whenever  the  abbreviated  reference  name  is  typed  and  expanded
  (CTRL/E), the original identifier string will appear in the buffer.

  The LSE commands used for the manipulation of aliases are:

       EXTRACT ALIAS alias-name
             selects the definition of the alias name and formats
             it as a command.

       DEFINE ALIAS name [value]
             specifies the alias name to be assigned and the value
             of the string to be referenced.

       DELETE ALIAS name
             specifies the alias name to be deleted.
