with COBOL v5, arrays can be unbounded, so the restriction on /V can be lifted for IDLs being used for COBOL.
Supports unbounded tables and groups to improve usability in defining variable length tables and groups In Enterprise COBOL for z/OS, V5.1, a new keyword UNBOUNDED is added to the OCCURS DEPENDING ON clause which enables you to define unbounded tables and groups.
With this new keyword, you no longer need to specify the maximum size for a table and the containing group. Usability in defining variable length tables in COBOL is improved particularly when you define COBOL group structures that correspond to XML documents.
