Copy and Restore Diskette
Purposes:
Deblock
Purposes:
To replace bad labels on an IBM 3540 Diskette Input/Output Unit.
To copy the entire contents of a diskette onto another diskette.
To eliminate the special records from all data files.
To create a backu p copy.
To block an 8OIB1·byte record file to a 344O-byte record file.
To deblock a blocked 3440·byte file in order to create an aO-byte SYSIN
file.
To copy files.
To print (list) job control statements and comments from a blocked input
file.
To select records (or a group of records) from a blocked 3440·byte file in
order to create an SO-byte SYSIN file.
Fast Copy Disk Volume
To copy the entire contents of an IBM 3330 Disk Storage, an IBM 3333
Disk Storage, or an IBM 3340 Direct Access Storage Facility onto another
disk device of the same type in a short time. The pack to be copied may
contain any combination of DOSIVS data sets and system components.
The contents of this disk may be copied directly to another disk device, or
it may be written on magnetic tape, to be restored at a later time. •
Initialize Data Cell
Purpose:
To prepare from one to five new or expired cells for use on
an
IBM 2321
Data Cell Drive.
Initialize Disk
Purpose:
To prepare one complete disk pack for use on an IBM 2311 Disk Storage
Drive, an IBM 2314 Direct Access Storage Facility, an IBM 2319 Disk
Storage, an IBM 3330 Disk Storage, an IBM 3333 Disk Storage, or an IBM
3340 Direct Access Storage Facility.
The program can also be used:
To change the volume label(s) and the VTOC (volume table of contents)
address of a previously initialized disk
pack
(other than an emulator pack).
If you specify IS in the input option parameter of the utility modifier
statement, surface analysis, HA (home address). and RO (track descriptor
record) generation are bypassed. This option assumes that a valid VTOC is
present. A work pack used for OS can therefore be converted into a work·
pack suitable to be used for DOSIVS.
Initialize Tape
Purposes:
Page 6-2
To write one to eight I BM standard tape volume labels in numerical se·
quence, followed by one dummy header label and one tapemark on EBeD IC
tapes.
