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

3704/3705 Control Program
Invoke the INSTEP EXEC procedure to load all the necessary files and
gen erat e the 3705 Assembler:
instep
The INSTEP EXEC procedure generates the 3705 Assembler and creates
the macro and text libraries that are needed to generate a 3704/3705 control program. The INSTEP EXEC procedure sends messages to the
terminal to indicate its progress. INSTEP issues the message BUILD STAGE ONE LOADING 'GEN3705 MACLIB' and uses the third tape file to create the CMS file GEN3705 MACLIB Al.
It issues the messages BUILD STAGE TWO MACLIBS LOADING 'MAC3705 using the fifth tape file to create the file MAC3705 MACLIB Al. Using the sixth tape file, INSTEP creates the CMS file OBJ3705 MACLIB Al, and issues the messages BUILD STAGE TWO TXTLIB LOADING 'OBJ3705 MACLIB' RENAME OBJ3705 MACLIB Al OBJ3705 TXTLIB Al Finally, INSTEP issues the message LOAD 3705 ASSEMBLR FILES and loads the assembler text files from tape via the TAPPDS command.
The files copied are listed off in messages in the form:
FILE 'fn EPTAPE Al' COPIED The ARNGEND EXEC procedure is invoked Assembler, after issuing the message BUILD 3705 ASSEMBLR MODULES. by INSTEP to generate
The ARNGEND EXEC procedure displays the following status and error
messages:
ENTER TARGET DISK MODE FOR 3705 ASSEMBLR MODULES DEFAULTS TO S-DISK IF NONE ENTERED You enter the mode letter of the disk that will contain the 3705 assembler modules when the assembler is used. This may be a different
disk then the one on which the modules now reside. If you enter a mode
letter, ARNGEND uses that mode letter as the "target.ode" operand of the
GENDIRT command when it creates the auxiliary directory for the 3705 assembler. If you do not specify a mode letter, S is assumed by the
GENDIRT command.
