  An array is a group of components  (called  elements)  that  all
  have  the  same  data  type  and  share a common identifier.  An
  individual element of an array is  referred  to  by  an  ordinal
  index  (or subscript) that designates the element's position (or
  order) in the array.

  Syntax:

     [[PACKED]] ARRAY [ {[[attribute-list]] index-type},... ] OF
         [[attribute-list]] component-type

  The 'attribute-list' is one or more  optional  identifiers  that
  provide information about the component type.

  The 'index-type' is the type of the  index,  which  can  be  any
  ordinal type or discriminated ordinal schema type.

  The 'component-type' is the type of the array components,  which
  can  be  any  type.   The  components of an array can be another
  array.

  Example:  ARRAY [0..4] OF INTEGER

  An array, whose components are themselves arrays,  is  called  a
  multidimensional  array.   An  array  can  have  any  number  of
  dimensions, and each dimension can have a different index type.

  Example:  ARRAY [0..4, 'A'..'D'] OF INTEGER

  This array is  declared  as  two-dimensional.   To  refer  to  a
  component  of  this  two-dimensional array, specify the variable
  name followed by the two bracketed index  values.   For  example
  X[0,'A']  or  X[0]['A'] specify the component in 'X' at position
  '0', 'A'.
