SET DEFINE Command
* RECFORM { F | U } Specifies the record format
If you include LABELS IBM, you must also specify
RECFORM.
F: Indicates fixed-length records (the default for ANSI
tapes).
U: Indicates undefined length (the default for IBM
tapes).
For input files, BLOCKLEN, RECFORM, and RECLEN
values are not checked for consistency. But if you enter
any of these attributes, the corresponding field in the
label must match, or the tape will be rejected.
For output files, if you do not specify BLOCKLEN,
RECFORM, or RECLEN for an IBM-standard labeled
tape, the open is rejected. For an ANSI-standard labeled
tape, these defaults are assumed:
RECFORM U
RECLEN 0
BLOCKLEN as configured for device
If you specify BLOCKLEN, RECFORM, and RECLEN for
a labeled-tape output file, label fields are generated with
those values.
* RECLEN record-length Specifies the record length of the tape file
For ANSI-standard tapes with RECFORM F, the default
RECLEN is the value configured for the device by
SYSGEN; if RECFORM is U, the default RECLEN is 0.
The record length can be in the range from 0 through
32767.
REELS volumes Specifies the number of volumes in a multivolume file
It is mandatory to specify this for any multivolume input
file. Specify an integer in the range from 0 through 255.
The default is 1.
* RETENTION days Specifies the retention period for the tape file
Specify an integer indicating number of days to retain
the tape file. This value is translated to an expiration
date when labels are written on the tape. The expiration
date prevents overwriting the tape contents. The default
is zero (the file expires immediately). If you specify
RETENTION, you must omit EXPIRATION. Specify an
integer in the range from 1 through 32767.
SYSTEM \node-name Gives the name of the system that contains the tape
drive specified in this DEFINE
If you include SYSTEM, you must omit DEVICE.
