Field Descriptions
Use
Use the Use field to specify how the tape file is to be used. The field options are:
The default value is OPENFLAG.
Density
Use the Density field to specify, in bits per inch (bpi), the data density of the tape. The
density can be 800 bpi, 1600 bpi, or 6250 bpi. The default density is the current setting
of the tape device.
Recform
Use the Recform field to specify the record format of ANSI-standard and IBM-standard
labeled tapes. The field options are:
For input files, values in the Recform, Blocklen, and Reclen fields are not required, and
the tape process does not check them for consistency. If you enter values in any of
these fields, however, the values in the corresponding label fields must match the
values in those three fields. Otherwise, the tape is rejected.
For output files, if you do not specify values in the Recform, Blocklen, and Reclen fields
for an IBM tape, the open is rejected. For an ANSI tape, the following values are
assumed:
Gen
Use the Gen field to specify, for ANSI-standard and IBM-standard labeled tapes only,
the generation group to which the file belongs. To specify the group, enter an integer in
the range 1 through 9999. The default value is 1.
IN Specifies that the tape file is to be read. If you specify this option, you must also
specify the tape volume ID in the Volumeid field and ANSI or IBM in the Labels
field. You cannot specify this option if you entered SCRATCH in the Volumeid
field.
OUT Specifies that data is to be written to the tape file.
EXTEND Specifies to append data to the tape file. If you specify this option, you must also
specify the tape volume ID in the Volumeid field and ANSI or IBM in the Labels
field. You cannot specify this option if you entered SCRATCH in the Volumeid
field.
EXTEND Specifies the type of access indicated by the access flag of the open call. The
flag must indicate read or write access.
F Specifies fixed-length records. If you specify this option, you must also specify a block
length that is a multiple of the record length.
U Specifies records of undefined length.
Recform U
Blocklen None
Reclen As configured for the device
