where n and m are integers and m is greater than n. The first format generates a single array element; the second generates a range of array elements. For example:

Embedded spaces are allowed within an array index but are not mandatory. In the second format, one of the integers can be omitted. Omission of the first integer implies n=1, and omission of the second implies m=K, where K is the significant length of the array.

Array indices cannot be used with text, displacement, or direction attributes but can be used with all positional codewords. Refer to Access Data from the Design or Catalogue Databases for further information.
