The DL/I features not supported are listed in the section Introduction of the ADL Installation documentation.
The ADL Consistency does not support the new extended Adabas control block (ACBX). Any call using the ACBX is forwarded to Adabas. This is in general no problem because Natural uses the ACBX only if the Adabas file makes use of expanded features (for example, spanned records, increased limits, or large object fields). And since ADL files do not contain expanded features, Natural uses the ACB when accessing migrated data.
