The keyword INZ(*LIKEDS) is allowed on a LIKEDS subfield. The LIKEDS subfield is initialized exactly the same as the corresponding data structure.
Keyword INZ is allowed on a LIKEDS subfield. All nested subfields of the LIKEDS subfield are initialized to their default values. This also applies to more deeply nested LIKEDS subfields, with the exception of nested LIKEDS subfields with INZ(*LIKEDS) specified.
If keyword INZ is coded on a main data structure definition, keyword INZ is implied on all subfields of the data structure without explicit initialization. This includes LIKEDS subfields.
