1. The variable must be subscripted, because only scalar-valued elements (integers, floating-point and character strings) are legal EQUEL values.

2. When the array is declared, the array bounds specification is not parsed by the EQUEL preprocessor. Consequently, illegal bounds values will be accepted. Also, when an array is referenced, the subscript is not parsed, allowing illegal subscripts to be used. The preprocessor only confirms that an array subscript is used for an array variable. You must make sure that the subscript is legal and that the correct number of indices are used.
