Array Reference

     (array) A special data value that allows access to an array.  In
     CA-Clipper, program variables and array elements cannot directly contain
     arrays; they may, however, contain array references.  A variable that
     contains a reference to a particular array is said to refer to that
     array, and the array's elements may be accessed by applying a subscript
     to the variable.  If the value of a variable containing an array
     reference is assigned to a second variable, the second variable will
     contain a copy of the array reference; both variables then refer to the
     same array, and the array's elements may be accessed by applying a
     subscript to either variable.
