IBM Mainframe–Payroll Project

Are you looking for mainframe projects?, then this is the right place for you. Right now I have 2  Projects  ( Mainframe projects with Source code ) coded with COBOL, have utilized LE xml service and GDGs. you might be able to tune these projects, so please post your valuable comments and snippets.

This is just a starting a series of mainframe projects, I’ll be uploading more projects in coming days. Also if you need a project or you have some suggestions please write to me at .

You might face few issues while uploading and running the applications and may think that the provided documentation is not enough. In those situations please drop me a mail at and I can help you to clear all the doubts regarding the projects.


This project is for generating calculating employee’s salary and generate pay slip. This application will also generate xml log for the pay slips generated and can be used to monitor in future by feeding to xml log monitoring application or you can even send it to a web service!.

I have coded these applications in my machine and xmitted and downloaded them.

Step 1. Download the binary format source and and dependent files.

We are no longer providing the download link in this page, the download link will be emailed everyone once they do the following steps.

1. Follow us on facebook

Click on the Like button on the facebook plugin.


2. Follow the blog.

Enter your email ID on the textbox and signup for the updates. Your email id will be stored in a secured area and it will not be visible to anyone. By signing up you  will be updated whenever new posts /projects are added to the website.


Once these two steps are done, you will be receiving and automated email with the Project download links. The Project source codes are free of cost and there is nothing will stop you from downloading the code.

The  zipped file contains a couple of binary files, download zip file and unzip it and keep the binary files in your local drive.

Step 2. Upload files to mainframe.

At this point of time I’m assuming that you have IBM personal communications installed in your machine, I mean any emulator is fine. Since I’m using PCOMM the I’m gonna explain from the PCOMM point of view ;).

Login to mainframe TSO session


Chose option 6 (command).


Now choose Actions from the Menu bar and select send file to host.


Click on browse and chose the first file from the zipped folder. and chose Binary as the transfer type for all files and click on update in list or add to list then click on send. Do not forget to put quotes before and after the server file name, this to avoid the automatic padding of your RACFID by zOS.

use the bellow server file name for all the respective files.


Step 3. Inflate the binary files.

Here we are expanding all the binary files to their original format, go to ISPF main option 6 (Command) and type

receive indsn(‘<binary filenames>’) , don’t forget the quotes

eg: receive indsn(‘PAYROLL.CLAIMFLE’)

you will get a message like below one, just press Enter key

INMR906A Enter restore parameters or ‘DELETE’ or ‘END’ + 

You will get a successful message like below. if not try again “ watch for the quotes”

INMR001I Restore successful to dataset ‘TSHRCI.PAYROLL.CLAIMFLE’

repeat the step 3 for all the 6 files there in the downloaded zip file.

Step 4. we are almost there, verify the files

go to ISPF option 3.4, and type “TSHRCI.PAYROLL” in dsname level and press enter you will get a screen almost like below. except TSHRCI.PAYROLL.PAYSLIP.GROUP  and TSHRCI.PAYROLL.XMLLOG.GROUP.


Step 5. Build the supporting GDGs

Go to TSHRCI.PAYROLL.JCLS and put an “e” in front of GDG and hit enter key.

right now this is the pay slip GDG JCL, so submit it to create pay slip GDGs

Now modify the JCL to below JCL (Changes are marked in red color) and submit it.

//SYSIN    DD   *
LIMIT(3)                -
NOEMPTY                 -
//         UNIT=SYSDA,
//         SPACE=(TRK,0),
//*        VOL=SER=EUTDSD,
//SYSUT1   DD *

//         SPACE=(TRK,5),
//*        VOL=SER=EUTDSD,
//         UNIT=SYSDA

Line marked in PINK color is the DASD volume, if your site is not SMS managed you have to provide the volume serial number, if you don’t know the vol ser, you can contact z box system admin.

Now if you go back to ISPF main option 3.4 and TSHRCI.PAYROLL.* you can see your screen as below.


Step 6. Time to review contents of all the datasets.

go to First file (TSHRCI.PAYROLL.CLAIMFLE) and you can see the below screen


This is the file which employees will claim their billed hours for a whole month. The structure is as given below

FD-CF-MONTH               PIC X(03).
FD-CF-WEEK                PIC X(01).
FD-CF-EMPID                PIC X(10).
FD-CF-BILL-CDE            PIC X(02).
FD-CF-SUN                    PIC X(03).
FD-CF-MON                   PIC X(03).
FD-CF-TUE                    PIC X(03).
FD-CF-WED                   PIC X(03).
FD-CF-THU                     PIC X(03).
FD-CF-FRI                      PIC X(03).
FD-CF-SAT                     PIC X(03).
First 3 chars for the month, Next 1 char for the week(1,2,3,4), next 10chars for employee id, entered ID should have an entry in TSHRCI.PAYROLL.EMPFILE, next 02 chars are for bill codes we can use bill code for claiming over time valid values( 01 for basic claiming, 02 for leave hours, 03 for week day overtime, and 04 for weekend over time) these bill codes should have matching entry in TSHRCI.PAYROLL.PAYFILE  with band code of the employee. Next 7 fields of 3 characters are for daily hour claiming.

e.g. JAN1100000000101000008008008008008000

says: its for Jan First week, for employee ID 1000000001, basic hrs, and 0hrs  for Sunday, 8 hrs each for Monday, Tuesday, Wednesday, Thursday, Friday and 0hr for Saturday.

Now go to TSHRCI.PAYROLL.EMPFILE, File structure is given below.

05  FD-EF-EMPID              PIC X(10).
05  FD-EF-FNAME             PIC X(10).
05  FD-EF-LNAME             PIC X(10).
05  FD-EF-ADD1                PIC X(10).
05  FD-EF-ADD2                PIC X(10).
05  FD-EF-PH                    PIC X(13).
05  FD-EF-DOJ                  PIC X(10).
05  FD-EF-DOB                  PIC X(10).
05  FD-EF-LASTPAYED      PIC X(10).
05  FD-EF-EMPMODE        PIC X(03).
05  FD-EF-STATUS            PIC X(03).
05  FD-EF-PAYMODE        PIC X(01).
05  FD-EF-BAND               PIC X(02).

First 10 bytes for employee id, next 10 for first name and next 10 for last name, next 10 for address line1 and next 10 for address line2, next 13 bytes for phone number, next 10 bytes for date of birth,, next 10 bytes for last paid month its for future enhancement. next 3 bytes for employment mode valid values are per for permanent and con for contract. next 3 bytes for status 001 is active and 002 is resigned, next 2 bytes for band can have any value but the band value should have a matching entry in TSHRCI.PAYROLL.PAYFILE.



This data set contains the file structures of all data sets, It has been created to refer the files at any point of time if you do not access to our web sites, and to avoid to messing up our code B)


This PDS contains the JCL’s for compiling our code, running our application, creating GDG’s and deleting GDG’s. GDG operations has been explained in Step 5.


This JCL can used to compile the cobol application, if the IGYWCL proc is in the ‘SYS1.ADMIN.PROCLIB’ and IGYWCL has been undergone some tweaks to accept member name, srce lib and load lib parms. right now this is the only cause in IBM internal training machines.


I believe this JCL must work in almost all the mainframes that has IBM Cobol version 4.1.  this job directly call the IGYWCl which is the part of COBOL ver 4.1 so  it should work without making any noises.

“If you have any issues with writing compile JCL for our project please write back to  me at  I can always help you to get a fully functional compile JCL”


This JCL is for executing our application. If you go to this JCL you can see that I have commented out a couple of lines (//*           VOL=SER=EUTDSD,) these are the volume serial numbers, since my machine is SMS managed I do not have to worry about the vol ser numbers, SMS will take care of it.

If your site is not SMS managed you have to un comment these line and change the volume serial number to the volume where GDGs resides. If you go to ISPF 3.4 option you can see volume at the right side of your dsn, see the below screen shot, for TSHRCI.PAYROLL.JCLS the vol ser is ETRU03.



These are the JCLS for creating and deleting GDGs. PLease refer to Step 5 for more information.


“Soon you opened the dataset please enter num off command in order to avoid any data lose”

This file is all about the MONEY, we have to declare the hourly charge for different bands.

File structure is

05  FD-PF-BAND                 PIC X(02).
05  FD-PF-HOURLY             PIC X(04).
05  FD-PF-DAILY                 PIC X(04).
05  FD-PF-MONTHLY           PIC X(06).
05  FD-PF-OVERTIME          PIC X(03).
05  FD-PF-LEAVE                PIC X(04).
05  FD-PF-WEEKENDOT     PIC X(03).

First 2 bytes are for Ban number, next 04 bytes are for per hour charge for normal (8hrs per day) work hours if the guy is working as per hour plan, next 4 bytes are for per hour charge normal (8hrs per day) work hours if the employee is working in daily wage plan, and next 4 bytes are for per hour charge for normal work hours(8hrs per day) if the employee is working in monthly wage plan. next 3 bytes are the amount needs to bill if the employee worked week day over time. Next 4 bytes are the amount needs to charge if the employee went on vacation ( normally no company will reduce any amount from salary, so we) . next 3 bytes are for the amount needs to charge if the employee worked on weekend over time.

e.g. 05020010000300003000200100

The above line says band is 05, 200 for hourly wage, 1000 for daily wage, 3000 for monthly wage, 300 if employee was on week day over time, 200 if employee was on leave/vacation, and 100 if employee worked on weekend over time.


PDS contains the source code, you have all the freedom to work on the source code.

Please do not change the Author name!

Step 7 Most important: create load lib

Load lib is the pds where our compile and exec pgm JCL are pointing to. So let create it. This PDS will be same for all our projects so don’t be a miser, allocate few cylinders.

Go to ISPF 3.2 screen fill the screen as below


press enter

Ignore the management class, storage class, volume serial, device type, data class and fill out the remaining fields as in below screenshots


Press enter to finish it up.


We are done with the setups. now lets go and run the code!.

Step 8. Run the code

If you want you can edit claim file, if you want to claim your own billed hrs. but don’t forget to add your own employees and band details also. Other wise app will abend!. :D. PLease be aware the code will work fine with the provided data.

Now go to TSHRCI.PAYROLL.JCLS and submit compile JCL


compile JCL should return MAXCC 0

after that submit EXECPGM jcl.


our program will return maxx cc 0, almost in all the cases, please review the data sets again if you have made any changes (Refer 5 and 6 to know the file structures and GDGs)

Go to spool and verify the claims processed  flow and the data (if needed)


Now, its the time review the GDGs

Pay slip

Go to ISPF 3.4, DSNAME level TSHRCI.PAY* and open the latest TSHRCI.PAYROLL.PAYSLIP.GROUP.* gdg.

and you can see the pay slips generated for our employees, of the inputted month.



go to ISPF 3.4, DSname level TSHRCI.PAY* and open the latest version of TSHRCI.PAYROLL.XMLLOG.GROUP


That’ is it. keep exploring the project, do tweaking, but do not forget to write to me your experiences and your doubts or what ever related to mainframes at

  1. Can you provide source code files in following extensions or request to suggest way to convert from existing files to the following extensions?

    COBOL programs are: *.cbl, *.cob and *.cobol
    JCL Jobs are: *.jcl
    COPYBOOK files are: *.cpy and *.copy
    JCL Procedures are: *.prc and *.proc
    JCL Includes are: *.inc

    1. The binary files very easy to expand in mainframe, please follow the does mentioned in the blog to upload files into mainframe and expand it into jcl input files and COBOL program. If you want to open or view files in windows please use XMITMANAGER application. It’s a free ware please google to download it.


  2. I am doing computer science engg with specialization in mainframe technology..and I find your website very helpful….I would like to view the payroll project that u have made.
