Cobol Sample Programs With Db2' title='Cobol Sample Programs With Db2' />One must understand the way COBOL works. Download Nissan Frontier 2004 Service Manual there. Computers only understand machine code, a binary stream of 0s and 1s. COBOL code must be converted into machine code using a compiler. Run the program source through a compiler. The compiler first checks for any syntax errors and then converts it into machine language. The compiler creates an output file which is known as load module. This output file contains executable code in the form of 0s and 1s. Evolution of COBOLDuring 1. In 1. 95. 9, COBOL was developed by CODASYL Conference on Data Systems Language. The next version, COBOL 6. In 1. 96. 8, COBOL was approved by ANSI as a standard language for commercial use COBOL 6. It was again revised in 1. COBOL 7. 4 and COBOL 8. In 2. 00. 2, Object Oriented COBOL was released, which could use encapsulated objects as a normal part of COBOL programming. Importance of COBOLCOBOL was the first widely used high level programming language. It is an English like language which is user friendly. All the instructions can be coded in simple English words. COBOL is also used as a self documenting language. COBOL can handle huge data processing. COBOL is compatible with its previous versions. COBOL has effective error messages and so, resolution of bugs is easier. Features of COBOLStandard Language. COBOL is a standard language that can be compiled and executed on machines such as IBM AS4. Business Oriented. COBOL was designed for business oriented applications related to financial domain, defense domain, etc. It can handle huge volumes of data because of its advanced file handling capabilities. Robust Language. COBOL is a robust language as its numerous debugging and testing tools are available for almost all computer platforms. Structured Language. Logical control structures are available in COBOL which makes it easier to read and modify. COBOL has different divisions, so it is easy to debug. COBOL Environment Setup. Try it Option Online. We have set up the COBOL Programming environment online, so that you can compile and execute all the available examples online. It gives you confidence in what you are reading and enables you to verify the programs with different options. Feel free to modify any example and execute it online. Try the following example using our online compiler available at Coding. Ground. IDENTIFICATION DIVISION. PROGRAM ID. HELLO. PROCEDURE DIVISION. DISPLAY Hello World. For most of the examples given in this tutorial, you will find a Try it option in our website code sections at the top right corner that will take you to the online compiler. So just make use of it and enjoy your learning. Installing COBOL on WindowsLinux. There are many Free Mainframe Emulators available for Windows which can be used to write and learn simple COBOL programs. One such emulator is Hercules, which can be easily installed on Windows by following a few simple steps as given below Download and install the Hercules emulator, which is available from the Hercules home site www. Once you have installed the package on Windows machine, it will create a folder like C herculesmvscobol. Run the Command Prompt CMD and reach the directory C herculesmvscobol on CMD. The complete guide on various commands to write and execute a JCL and COBOL programs can be found at www. Hercules is an open source software implementation of the mainframe System3. ESA3. 90 architectures, in addition to the latest 6. Architecture. Hercules runs under Linux, Windows, Solaris, Free. BSD, and Mac OS X. A user can connect to a mainframe server in a number of ways such as thin client, dummy terminal, Virtual Client System VCS, or Virtual Desktop System VDS. Every valid user is given a login id to enter into the ZOS interface TSOE or ISPF. Compiling COBOL Programs. In order to execute a COBOL program in batch mode using JCL, the program needs to be compiled, and a load module is created with all the sub programs. The JCL uses the load module and not the actual program at the time of execution. The load libraries are concatenated and given to the JCL at the time of execution using JCLLIB or STEPLIB. There are many mainframe compiler utilities available to compile a COBOL program. Some corporate companies use Change Management tools like Endevor, which compiles and stores every version of the program. This is useful in tracking the changes made to the program.

In the above example, RMODE instructs the compiler to use relative addressing mode in the program. The COBOL program is passed using the SYSIN parameter. Copybook is the library used by the program in SYSLIB. Executing COBOL Programs. Given below is a JCL example where the program MYPROG is executed using the input file MYDATA. URMI.

This is important to note that the above JCL can be used for a non DB2 COBOL module only. Executing COBOL DB2 programs. For running a COBOL DB2 program, a specialized IBM utility is used in the JCL and the program DB2 region and required parameters are passed as input to the utility. The steps followed in running a COBOL DB2 program are as follows When a COBOL DB2 program is compiled, a DBRM Database Request Module is created along with the load module. The DBRM contains the SQL statements of the COBOL programs with its syntax checked to be correct. The DBRM is bound to the DB2 region environment in which the COBOL will run. This can be done using the IKJEFT0. JCL. After the bind step, the COBOL DB2 program is run using IKJEFT0. DBRM library as the input to the JCL. STEP0. 01 EXEC PGMIKJEFT0. STEPLIB DD DSNMYDATA. URMI.

Please note that the program name, DB2 Sub System Id SSID, and DB2 Plan name are passed within the SYSTSIN DD statement. The DBRM library is specified in the STEPLIB. COBOL Program Structure. A COBOL program structure consists of divisions as shown in the following image A brief introduction of these divisions is given below Sections are the logical subdivision of program logic. A section is a collection of paragraphs. Paragraphs are the subdivision of a section or division. It is either a user defined or a predefined name followed by a period, and consists of zero or more sentencesentries. Sentences are the combination of one or more statements. Sentences appear only in the Procedure division. A sentence must end with a period.
