Section 4. VM/370 Service Programs Controlling the 3704/3705 Communications Control Program
operational control of the 3704/3705 Communications Controller (hereinafter referred to as 3705) resides with the system operator via
the NETWORK command. In addition, the behavior of the 3705 device is,
for a large part, dependent upon the communications control program with
which it was loaded. The ,communication control programs are created,
assembled, or modified by a set of CftS co.mands specifically designed
for this purpose. These commands are: 1583705 GEN3705 LIED SIVENCP ZAP The cited 3705 NETWORK the V8/370 publication.
co •• ands, described in greater detail in the V8/370 Guide, are the systea prograaaer's responsibility. The and NCPDUftP comaands, however. are the responsibility of system operator and are described elsewhere in this
The 3704/3705 Dynamic Trace Facility is supported for virtual machine operation. However, if the 3704/3705 in emulator mode is not dedicated
to the user invoking the the user is required to have in his
directory a privilege class other than (or in addition to) G.
Using CMS To Alter VM/370 Files The Y8/370 system operator is usually assigned a virtual machine with a large DISD storage allotment. This DISD storage can be assigned to
other users as a temporary work area or for short-tera DISD storage. In
addition, the operator's virtual machine can record system statistical
data, or create and maintain directory files and other system files.
For whatever reason the operator uses the system, it is probable that some files will need to be modified at some time. One of the easiest ways to modify such systea files is to use the CftS Editor (EDIT)
facilities.
The Cft5 EDIT facilities provide ways to create and modify all types
of C8S files. For a complete description of the and
co •• ands, see the !!1L11Q Guide and the VSL11.Q tilS' .. ,!nd OTHER C8S C0881NDS There may be occasions, caused by user demands, when other facilities of CftS .ay be invoked. For example, to create punched output of a file for
use by another system, or to create a history file. The co •• ands likely
to be needed by the system operator are the following:

How To Use It Use the D1SD Dump Restore (DDR) program to dump, restore, copy, or print YB/370 user minidisks. The DDR program may run as a standalone program, or under CBS via the DDR co.mand. The DDR program has five functions:
1. Dumps part or all of the data from a D1SD device to tape.
2. Transfers data from tapes created by the DDR dump function to a
direct access device. The direct access device must be of the same type as that which originally contained the data.
3. Copies data fro. one device to another of the same type. Data may be reordered, by cylinder, when copied from disk to disk. In order
to copy one tape to another, the original tape must have been
created by the DDR DUftP function.
q. Prints selected parts of DASD and tape records in hexadecimal an')
EBCDIC on the virtual printer.
5. Displays selected parts of DASD and tape records in hexadecimal ana EBCDIC on the terminal. To generate the YB/370 starter system from the distribution tape, th, standalone RESTORE function Jitistbe used. IBYOKIBG DDR UNDER CftS The format of the DDR co •• and is: r ,

fn ft Ifal 1* I L .. I! I L .t is the identification of the file containing the control statements for the DDR program. If no file
identification is provided, the DDR program attempts to
obtain control statements from the console. The filemode defaults to an asterisk (*) if a value is not provided.
