Format for Variable Length Records

Offset Type Field
Dec Hex
0 0 BINARY(4) Number of variable length records
These fields repeat for each variable length record. BINARY(4) Length of variable length record
BINARY(4) Key
BINARY(4) Length of data
CHAR(*) Data

If the length of the data is longer than the key field's data length, the data is truncated at the right. No message is issued.

If the length of the data is smaller than the key field's data length, the data is padded with blanks at the right. No message is issued.

It is not an error to specify a key more than once. If duplicate keys are specified, the last specified value for that key is used.

Each variable length record must be 4-byte aligned. If not, unpredictable results may occur.


Field Descriptions

Number of variable length records. The number of records. Only specific attributes can be changed. Refer to Valid Keys for more information.

Length of variable length record. The length of each record. Only specific attributes can be changed. Refer to Valid Keys for more information.

Key. The key specifies either the library or folder attribute. For the list of valid keys, see Valid Keys.

Length of data. The length of the data that is used to specify the value for the given parameter.

Data. The data that is used to specify the value for the given key.

The following table lists the valid keys for the key field area of the variable length record. For detailed descriptions of the keys, see Field Descriptions.

Key Type Field
1 CHAR(*) Library
2 CHAR(*) Folder


Field Descriptions

Folder. The backup type selected and the list of folder objects to have their backup type changed. For the format of this field, see Folder Key Format.

Library. The backup type selected and the list of library objects to have their backup type changed. For the format of this field, see Library Key Format.


Folder Key Format
