specifies any valid
specific device number, as well as DASD, DISK, OTHER, SYSOUT, TAPE,
and TERM.
DASD or DISK
indicates that the
specified value is to be used as the default block size for all types
of tape devices.
OTHER
specifies the value
that SAS uses when it is unable to determine the exact device type.
SYSOUT
sets values for SYSOUT
data sets.
TAPE
sets values for the
3400, 3480, 3490E, and 3590 device types.
TERM
sets values for data
sets that are directed to the terminal.
value
specifies the default
block size. Valid values are
number
specifies the block
size that SAS is to use for the device.
OPT
tells SAS to choose
an optimum block size for the device.
MAX or FULL
tells SAS to use the
maximum permitted block size for the device.
HALF, THIRD, FOURTH, or FIFTH
instructs SAS to use
the largest value that results in obtaining two, three, four, and
five blocks per track, respectively (if a disk device), or the maximum
permitted block size divided by two, three, four, and five, respectively
(if not a disk device).
MIN
specifies the same
as FIFTH above.
Details
The minimum value for
FILEBLKSIZE(device-type)= is
5; the maximum value is device dependent and can be obtained by using
the DEFINE option in the PROC OPTIONS statement. For example:
