Overview

Package adatypes is used to define types use for parsing Adabas field definitions tables. It contains Adabas and Natural DDM like Map definitions. It converts Adabas types to GO types and vice versa. In addition it contains basic functions used to handle logging facilities and Adabas buffer parsing and generation.
