3104/3105 Control Program
Generating and Loading the 3704/3705 Control Program Several commands and EXEC procedures generate and load the 3104/3105 control program. These commands and EXEC procedures are executed in a eMS virtual machine. The commands are a part of the VM/310 system and
are distributed with it. A special version of the IBM 3104/3105 Network Support Package for OS/VS, Order No. 5144-ANl EP/VS from PID for use under VM/310. This version of the
contains two CMS EXEC procedures for generating 3704/3705 control programs.

This section describes the step by step procedure for generating and
loading the 3704/3105 control program. Each EXEC procedure and command
is described as it is used. The action required at each step is
summarized first and then explained in detail. The preceding "Planning
Considerations" section, lists all the documentation, physical devices,
programming, and other materials you need before starting to generate
the 3 7 04/3705 control program. Step 1. Log On the VM/370 System VM/370 supports the EP type of control program. The VM/370 system that
you load also must have been generated with: • The IBM 3104 or 3105 Communications Controllers specified on a RDEVICE system generation macro. • The NAMENCP macro coded to create an entry in the VM/310 system name
table (DMKSNT) for the 3104/3105 control program. • Space reserved on a CP-owned volume to contain a copy of the 3704/3105 control program.
These VM/310 system generation requirements are described in Part 1. Step 2. Set Up a eMS Virtual Machine You must IPL a CMS virtual machine and be sure that the necessary
devices are attached.
The 3104/3105 control program is generated using commands and EXEC procedures that execute in a CMS virtual machine. The C8S virtual
machine must have the following resources: • At least 1024K of virtual storage. • One tape drive (9 track, 800 or 1600 bpi). • Space available on the C8S A-disk (120 cylinders of a 3330 disk, all 203 cylinders of a 2314 disk, 300 cylinders of a 3340 disk, or 60 cylinders of a 3350 disk.
Part 4. Generating the 3104/3105 Control Program 291

3704/3705 Control Program If the CftS virtual machine does not have these resources, use the CP DEFINE command to redefine the size of your virtual storage or send a
message to the operator requesting him to attach the tape or disk device
you .need.
Be sure that there are no files on the A-disk with a filetype of COpy or TEXT. Use the CftS RENAftE command to temporarily change such
fi1etypes. A naming conflict can terminate the installation procedure
for the distribution tape. You need CP command privilege classes A, B, and G to install the 3704/3705 control program and, if you use the NETWORK TRACE command
while testing the 3704/3705 control program, you need command privilege
class F. Do not use class F unless you need it; for class F, I/O error
recording is not done automatically. Check wi th the system
administrator to ensure that your Vft/370 directory entry has the
appropriate command privileges. Step 3. Load the IBM 3704/3705 Control Program
Distribution Tape Files onto a eMS Disk Use CMS commands to position the distribution tape at the proper file
and to create CftS disk files from the tape files. The first file
created from the files is an EXEC procedure that processes the rest
of the tape files and creates the CftS disk files.
If you cannot mount the distribution tape yourself, send a message to
the operator and have him mount the correct tape. The distribution tape
contains ten files. The tenth file contains the INSTEP and ARNGEND EXEC procedures, which create the necessary CMS files from the other tape
files. Use the CftS TAPE command to position the tape at the beginning of the
tenth file:
tape fsf 9
Then, use the CftS TAPPDS command to create the INSTEP EXEC A1 and
ARNGEND EXEC A1 files from the tenth file:
tappds * exec
If the files are successfully created, the responses
FILE ' ARNGEND EXEC A1' COPIED FILE • DftS ARD EXEC A 1 ' COPIED FILE 'DMSARX EXEC A1' COPIED FILE 'DMSGRN EXEC A1' COPIED FILE 'DMSTMA EXEC Al' COPIED FILE 'INSTEP EXEC A l' COPIED appear on the terminal. Before you invoke the INSTEP EXEC procedure,
you should obtain access to mode 1 files on the CftS system disk. You can do this by accessing it as an extension of your A-disk; for example,
if the S-disk is at virtual address 190, and you currently have a disk
accessed as mode C, you issue the command
access 190 cia 298 IBft VM/370 Planning and system Generation Guide
