Description
Overview
This assignment is in two parts, each worth 50 points. The first part consists of assembling and executing an
Assembler program and the second consists of compiling and executing a COBOL program.
You will turn in two (2) text files of output from this assignment. One of the text files will be for Part A,
the COBOL Compiler part, and the other will be for Part B, the Assembler part. This assignment’s objective
is to give you more experience writing and running basic JCL jobs on the Marist mainframe.
Note: Although you will not be required to document either of the programs given to you, please review
the JCL documentation guidelines in the Documentation and Coding Guidelines in Course Documents on
Blackboard and document your own JCL adequately and appropriately. Inadequate documentation will
result in deducted points. Be sure to include the double forward slashes by themselves at the bottom of
each job file too!
Part A – COBOL (50 points)
For Part A of the assignment, the source code of a simple complete COBOL program is provided for you
as . This file is included in the assignment folder on Blackboard. Use the COBOL Compiler
for the first step of the job you are writing.
Using IDz, you can copy and paste the entire COBOL program provided to you as a text document into a
new member of your PDSE named . Once you get the program copied into IDz’s
editor, you can build the JCL around it. Your task is to create a complete JCL job stream to 1) compile, 2)
bind, and 3) fetch and execute this small COBOL program as an in-stream program.
Programming Notes:
• The first step of both this job will be the COBOL Compiler step, the second will be the Binder step,
and the third will be a fetch and execute step.
• Use the following COBOL compile parameters on the COBOL compile step:
See the course notes for an explanation of these parms.
These parameters will be necessary throughout the semester on any COBOL Compiler steps of your
JCL.
• Due to some changes this past summer at Marist, the COBOL Compiler step will require a STEPLIB
of:
• Write the object module from the COBOL Compiler step to a temporary data set that will be passed to
the Binder step. Again, use the characteristics for this temporary data set provided in the COBOL
Compiler part of the notes titled 3. COBOL Compiler, Assembler and Binder.

• Write the program object (load module) that comes out of the Binder step to your own PDSE named
that you created when you ran your Assignment 1 JCL. The name of the program object
member should be exactly the same as the name of the program itself.
• Follow the Binder step with a third step that fetches and executes your program object.
• Do not execute either the Binder step or the fetch and execute step unless the return code from the
above steps is zero (0).
• The name of the input file is:
The input card for this file for the COBOL program must be named .
• The output card for the COBOL program must be named . This output should be written
to standard output.
• The output you turn in should have correct output, and all three return codes should be 0000. The return
codes are in the center of about lines 6, 7, and 8 of the JES2 Job Log (second printed page). You should
see return codes of 0000 for each of the COBOL Compiler, Binder and fetch and execute steps.
Part B – High-Level Assembler (50 points)
For Part B of the assignment, the source code of a simple complete Assembler program is provided for you
as . This file is included in the assignment folder on Blackboard. Use the High-Level
Assembler for the first step of the job you are writing.
Once again, using IDz, you can copy and paste the entire program into a new member of your
PDSE named . Once you get the program copied into IDz’s editor, you can build the JCL around
it. Your task is to create a complete JCL job stream to 1) assemble, 2) bind, and 3) fetch and execute this
small Assembly Language program as an in-stream program.
Programming Notes:
• The first step of this job will be the High-Level Assembler step, the second will be the Binder step, and
the third will be a fetch and execute step.
• Be sure to add to the card of the Assembler step. This parameter will be necessary
throughout the semester on any Assembler steps of your JCL.
Note: tells the Assembler to produce the assembly listing using American National Standard
(ANSI) printer-control characters. (If is specified the Assembler uses machine printer-control
characters. We want the version.)
• Write the object module from the Assembler step to a temporary data set that will be passed to the
Binder step. Use the characteristics for this temporary data set provided in the Assembler part of the
notes titled 3. COBOL Compiler, Assembler and Binder.

• Write the load module that comes out of the Binder step to PDSE named that you created
when you ran your Assignment 1. The name of the load module member should be exactly the same
as the name of the program itself.
• Follow the Binder step with a third that fetches and executes your program object.
• Do not execute either the Binder step or the fetch and execute step unless the return code from all
previous step(s) steps is zero (0).
• The name of the input file is the same as that for the COBOL program above:
The input card for this file for the Assembler program must be named .
• The output card for the Assembler program must be named . This output should be written
to standard output.
• Like in Part A, the output you turn in should have correct output, and all three return codes should be
0000. The return codes are in the center of about lines 6, 7, and 8 of the JES2 Job Log (second printed
page). You should see return codes of 0000 for each of the Assembler, Binder and fetch and execute
steps.
IMPORTANT
Be sure to follow ALL of the JCL Documentation Standards as described in the Documentation and Coding
Guidelines. (Hint: Get one of the two jobs working and completely documented first, then use it as a guide
for the second part.)
What To Turn In
Use Retrieve Jobs to get your output down from the Marist output queue onto your PC. Submit the two (2)
files named and on Blackboard.
