FDDM - Natural System File for DDMs

This Natural profile parameter is used to specify five subparameters for the Natural system file for DDMs.

Possible settings See FDDM Parameter Syntax.
Default setting none  
Dynamic specification yes  
Specification within session no  

Notes:

  1. If this system file is defined, all DDMs are stored on the specified path. DDMs stored in libraries will no longer be accessible from Natural. This is similar to Natural on mainframes, where all DDMs are stored in the system file FDIC.
  2. If the FDDM system file is undefined (database-ID and file-number = 0), the DDMs are stored in the libraries as supplied before. The system file FDDM is displayed as an inactive environment.
  3. For information on system files, refer to: System Files in the Natural Operations documentation.

FDDM Parameter Syntax

The parameter syntax is as follows:

FDDM=(database-ID,file-number,password,cipher-key,RO)

Where:

Syntax Element Value Explanation
database-ID 1 - 65535 Database identification of the database in which the Natural system file for DDMs is located.

Note:
Database ID 255 is reserved for logical system files for Software AG products, see Natural profile parameter LFILE.

file-number 1 - 5000 File number of the database file in which the Natural system file for DDMs is located.
password 1 - 8 characters The password is only required if the Natural user-program system file has been password-protected using the Adabas security feature.

Note:
The password is reserved for future use; currently, it is ignored.

cipher-key 1 - 8 numeric characters The cipher key is only required if the Natural user-program system file has been ciphered using the Adabas security feature.

Note:
The cipher key is reserved for future use; currently, it is ignored.

RO - Indicates that the Natural user-program system file is "read-only" and is only specified if modifications on the file are to be disabled.

Examples:

FDDM=(22,5)
FDDM=(22,5,,12345)
FDDM=(22,5,,,RO)
