To achieve the same sort or retrieval sequence under DB2 as under the file system, place a BINARY XFD directive immediately before each key field that contains signed numeric data. High values and low values can cause problems in key fields. If you want data that uses the BINARY XFD directive to be stored as hexadecimal encoded CHAR types, you can specify A_DB2_USE_CHAR_FOR_BINARY in the ACUCOBOL-GT runtime configuration file.
Other limits are described in Limits and Ranges of the ACUCOBOL-GT documentation.
