/UNDEFINED_FAT=record-format:[record-attributes:][record-size]
Establishes default file attributes to be used for records on ISO
9660 media for which no record format has been specified.
The following table describes the parameters:
Parameter Description
record- Specifies the format for all records in a file:
format FIXED, VARIABLE, STREAM, STREAM_LF, STREAM_CR, LSB_
VARIABLE, or MSB_VARIABLE. For a description of
these record formats, see the discussion of the RMS
field FAB$B_RFM in the OpenVMS Record Management
Services Reference Manual.
record- Specifies the attributes for all records in a file:
attributes NONE, CR, FTN, PRN, NOBKS. Applies only to non-
STREAM record formats. For a description of these
record attributes, see the discussion of the RMS
field FAB$B_RAT in the OpenVMS Record Management
Services Reference Manual.
record-size Specifies the maximum record size for all records
in a file: 0 to 32767. Applies only to FIXED
or STREAM record formats. For a description of
possible RMS record sizes, see the discussion
of the RMS field FAB$W_MRS in the OpenVMS Record
Management Services Reference Manual.
ISO 9660 media can be mastered from platforms that do not support
semantics of files containing predefined record formats. The
/UNDEFINED_FAT qualifier establishes default file attributes to
be used for records on ISO 9660 media for which no record format
has been specified.
The /UNDEFINED_FAT qualifier is valid only in conjunction with
the /MEDIA_FORMAT=CDROM qualifier.
This qualifier temporarily overrides all undefined file types,
replacing them with selectable record formats having selectable
record attributes and selectable record sizes as shown in the
following illustration:
{ FIXED:record-attributes[, . . . ]:record-size}
{ VARIABLE:record-attributes[, . . . ] }
{ STREAM:record-size }
record formats { }
{ STREAM_LF:record-size }
{ STREAM_CR:record-size }
{ LSB_VARIABLE:record-attributes[, . . . ] }
{ }
{ NONE - None }
{ CR - Carriage_return }
record_attributes { FTN - Fortran }
{ PRN - Print }
{ }
{ NOBKS - No-Block-Span }
record_size { 1 to 32767 }
Example
In the following example, the volume labeled OFFENS is mounted on
DKA1 and all files on the volume are defined to be fixed length,
carriage return, and 80 bytes in length. MOUNT also assigns the
logical name STRAT.
$ MOUNT/MEDIA_FORMAT=CDROM/UNDEFINED_FAT=(FIXED:CR:80) DKA1: OFFENS STRAT
