2.3 Association of names with elementary components

In view of a future identification, it is possible to associate an integer type name with one, or a group of, elementary components. This association is done using the following subroutines:

•       SUBROUTINE BGNAS(N)
        INTEGER N
  

  associates   the name N with the elementary components which follow.

•       SUBROUTINE ENDAS
  

  indicates the  end of the preceding sequence.

It is possible to nest the BGNAS and the ENDAS. For example, the sequence:

      CALL BGNAS(1)
         ....
         CALL BGNAS(2)
            ....
            CALL BGNAS(3)
              ....
            ENDAS
            ....
         ENDAS
         ....
      ENDAS

is identical to the following sequence:

      CALL BGNAS(1)
        ....
      CALL ENDAS 

      CALL BGNAS(2)
        ....
      CALL ENDAS 

      CALL BGNAS(3)
        ....
      CALL ENDAS 

      CALL BGNAS(2)
        ....
      CALL ENDAS 

      CALL BGNAS(1)
        ....
      CALL ENDAS

There cannot be more than ten levels of nesting.

This identification possibility is not available on all terminals.
