Command information entries

This table describes the format of the command output for the SAV and RST commands.

Command information entries are output in the format described in the table below. The entry type value in the header determines if the entry associated with the header is a command information entry.

The system associates a coded character set identifier (CCSID) with all data. This association is maintained across all save and restore operations.

For each field, an offset is specified in bytes. This offset is relative to the base address of the entry, or the beginning of the first field in the entry header.

Notes:
  1. Set by column. The following column values indicate which operations write the content of the field into the output:
    Value
    Condition
    S
    Save operation set this field.
    R
    Restore operation set this field.
    S/R
    Either operation set this field.
    (blank)
    Not set by either operation. The associated field is set to zero for numeric fields, blank for character fields, or empty for variable-length character fields.
  2. Format of device name. You can find the first entry using the Device name offset field to get to the Number of device name field. The Number of device names field is not repeated.
    Type (in bytes) Content Field
    BINARY(4) (blank) Number of device identifiers

    Then, moving to the first device identifier. Each device identifier consists of a length followed by its name. The device name fields are repeated for each device identifier.

    Type (in bytes) Content Field
    BINARY(4) S/R Device name length
    CHAR(*) S/R Device name
  3. Format of file label. You can find the start of the file label using the File label offset field. The file label fields are not repeated.
    Type (in bytes) Content Field
    BINARY(4) S/R File label length
    CHAR(*) S/R File label
