Since it is sample program and the intention is to describe the flow of Cobol-DB2 program, I haven’t included the cursors or complex sql statements on our program, I’ll be adding more programs in coming days. Step 4 Compile and BIND COBOL-DB2 Program. Above Diagram is pretty well describes the whole process of compiling a cobol DB2 program. COBOL Demonstration Program The following (CUQCP1C1.cbl) is a sample of the COBOL demonstration program that processes a table one row at a time. The program uses the SQL FETCH statement to sequentially access the rows in the table. IDENTIFICATION DIVISION. SIMOTIME TECHNOLOGIES.
- Selected Reading
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. Virtual dj music mix download. 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 sentences/entries.
- Sentences are the combination of one or more statements. Sentences appear only in the Procedure division. A sentence must end with a period.
- Statements are meaningful COBOL statements that perform some processing.
- Characters are the lowest in the hierarchy and cannot be divisible.
You can co-relate the above-mentioned terms with the COBOL program in the following example −
Divisions
A COBOL program consists of four divisions.
Identification Division
It is the first and only mandatory division of every COBOL program. The programmer and the compiler use this division to identify the program. Manual usuario casio edifice efa 1190. In this division, PROGRAM-ID is the only mandatory paragraph. PROGRAM-ID specifies the program name that can consist 1 to 30 characters.
Try the following example using the Live Demo option online.
Given below is the JCL to execute the above COBOL program.
When you compile and execute the above program, it produces the following result −

Environment Division
Environment division is used to specify input and output files to the program. It consists of two sections −
- Configuration section provides information about the system on which the program is written and executed. It consists of two paragraphs −
- Source computer − System used to compile the program.
- https://clevernv593.weebly.com/dirty-projectors-bitte-orca-blogspot-rar.html. Object computer − System used to execute the program. https://clevernv593.weebly.com/download-hypnotized-slowed-young-jeezy-download-preactivated-version.html.
- Input-Output section provides information about the files to be used in the program. It consists of two paragraphs −
- File control − Provides information of external data sets used in the program.
- Djay full version download. I-O control − Provides information of files used in the program.
Data Division
Data division is used to define the variables used in the program. It consists of four sections −
- File section is used to define the record structure of the file.
- Working-Storage section is used to declare temporary variables and file structures which are used in the program.
- Local-Storage section is similar to Working-Storage section. The only difference is that the variables will be allocated and initialized every time a program starts execution.
- Linkage section is used to describe the data names that are received from an external program.
COBOL Program
The JCL to execute the above COBOL program is as follows −
When you compile and execute the above program, it produces the following result −
Procedure Division
Sample Cobol Db2 Program
Procedure division is used to include the logic of the program. It consists of executable statements using variables defined in the data division. In this division, paragraph and section names are user-defined.
There must be at least one statement in the procedure division. Panasonic kx-t7735 user manual set time. The last statement to end the execution in this division is either STOP RUN which is used in the calling programs or EXIT PROGRAM which is used in the called programs.
