PROCESS-PERSON. the structure of the program reflects the structure of the file. - Bill Woodger Feb 26 '15 at 14:28. Compare records of two flat files and write the un-matching record of FILE-1 to Output to implement ur compare logic in cobol program u can follow this logic. Step1: in FD section declare copybook of old file as it is. then declare the copybook of new file (which is same as old file) with Replacing option (replacing option is used to differentiate between 2 files.. no impact on logic) also declare the record structure for o/p file

I have two input files, each with length of 5200 bytes. A seven byte key is used to compare both files, if there is a match then it needs to be written to match file but while writing to match file I need a few fields from infile1 and all other fields from infile2.. If there is no match then write to no match file.. Is it possible to do it in sort?I know it can be easily done using COBOL. Comparing 2 files and writing matched and unmatched records into 2 different files is the very basic program for any development projects using COBOL as programming language. Below program compares the given 2 files and writes the unmatched records into output

Now i want to compare file1 & file2 based on ENO,the matching recoreds should write in outfile3 along with duplicates and unmatched records in outfile4. Kindly help me out. I have written code,but couldnt able to move duplicates in outfile3.Kindly correct me. ID DIVISION. PROGRAM-ID. COMPARE. ENVIRONMENT DIVISION. INPUT-OUTPUT SECTION. FILE. The first job will compare two files that are identical. The second JCL job will compare two files that have a difference embedded within the files. The Data File Compare programs will find the difference and produce a NOT-Equal result. Compare Result is Equa

SimoZAPS will generate the COBOL source code for a program that will compare two data files. The generated program may be compiled and executed in a Mainframe or Micro Focus environment. We have made a significant effort to ensure the documents and software technologies are correct and accurate Do not do 2 sort using/givings an a program - actually, 1 using/giving is poor coding practice. . . If there is work to be done in an input or output procedure, the internal sort is often an excellent choice. To merely put some data in a sequence, the external sort is a better choice COBOL File Handling supports 3 types of files i.e Sequential File,Indexed File, and Relative organization File. To store the data in COBOL in form of DISK or TAPE we use files. Sample COBOL Program to show how the file is defined in INPUT-OUTPUT Section for comparing text files). There are also many switches provided with them (especially for Diff for VAX/Alpha VMS computers) If you have to do comparing in your COBOL program, try to read files alternatively: OPEN INPUT FILE1 FILE2. (output file3) MOVE 0 TO END1 END2. PERFORM COMPARE-IT UNTIL END1 = 1 OR END2 = 1. THE-END. CLOSE FILE1 FILE2.

Suppose the input file data available in the input.txt file contains the following JCL to execute the above COBOL program <= or >=] rec-key INVALID KEY DISPLAY 'Invalid Key' NOT INVALID KEY DISPLAY 'File Pointer Updated' END-START. Close Verb. Close verb is used to close a file. After performing Close operation, the variables in the. Sequentially read a specific record in a file then display it. cobol. Bruce Martin is correct. The only sensible way to do this, where you have to display information after each input, is with an indexed file. However, it may be an exercise you have to complete using a sequential file. First, you need a single process to drive your program.

File opened with Extend Mode appends the writing records at the end of the file. In COBOL program there is no much difference between these two types. If you are accessing ESDS VSAM file, then in COBOL program should coded like this. SELECT FILE ASSIGN TO AS-DDNAME. Actually DD name matches with JCL DD Name PROGRAM-ID. HELLO. DATA DIVISION.

Comparing two files and write unmatched fields to output

Match Merge logic is extensively used in COBOL programs to compare the data in two sequential files effectively. Only pre-requisite to for using this logic is, all input files to be in Sorted Order Problem : I have 2 Sequential files File 1 and File 2 This program wiil count the records then call another program that will reserve a sequecnce of numbers. This program then writes the starting number to a VSAM record that can be picked up by Post (vendor software) that will number each record. Really uncomplicated but I would like to have one program to handle all of the various files

Below are COBOL date functions to add, Subtract and Find the duration between Dates, Times and Time stamps. 1. ADD-DURATION. This is rarely seen in our programs but really a helpful Intrinsic function that COBOL provided. This is to add a specific duration to a date/time variable/value Powerful File Comparison Comparex, available on z/OS, z/VM, and z/ VSE platforms, is the most powerful tool on the market for comparing data, text, and direc - tory files. The product performs fast, accurate, single-step comparisons of the contents of vir - tually any two-file types—libraries, directories, sequential files, or databases Before your program can access the data in an input file or place data in an output file, you must make the file available to the program by OPENing it. When you open a file you have to indicate how you intend to use it (e.g. INPUT , OUTPUT , EXTEND ) so that the system can manage the file correctly

  1. File Descriptors. The DATA DIVISION of a COBOL (sub)program contains two sections, the FILE SECTION and the WORKING-STORGAGE SECTION. The latter is used to describe, via data description entries (level numbers, PICTURE clauses, etc.), the hierarchical structure of data items that exist during execution of the program
  2. The second approach is very similiar to approach #1 - the difference is that two input files are involved. The first input file will contain the data for the table and the second input file will contain the regular data. Therefore there will be two selects and two Fds, one for each file. FD TABLE-FILE DATA RECORD IS TABLE-INPUT. 01 TABLE-INPUT
  3. Data Items - User defined variables: The main objectives of the chapter are: Identify the various data items in a COBOL program. Example 1: 05 W01-STRING PIC X(20) VALUE 'ABC'

Data File Compare of Two Sequential Files with 80-Byte Record

Compare two Record Sequential Files with 80 Byte Record

  1. A COBOL layout is comprised of a line for each field or group. A COBOL field definition gives the level (discussed later), field name, and a picture, or PIC clause, which tells you the data type or data category of the field, and its size. The three data types you are likely to see are
  2. Records within master files are typically stored in ascending sequential order on a unique key field. Transaction files contain one or more recent records that should be applied to the master file. Sequential updating of the Master file requires that the transaction file is in the same key field order as the master file
  3. then we can use diff to automatically display for us which lines differ between the two files with this command: diff file1.txt file2.txt and the output will be

  1. I could give this a subtitle: How to put a bad date in a date field, but this is not the reason of this post, just an accidental discovery. Having previously written about how to use database files in a CL program I have to mention using display files in CL.. You cannot use CL for anything as complex as a subfile.But you can for what I call report submission screens, you know the type: a.

How to create the sort step to create the desired output in a separate file as given below. IC2/I.B.A. Effective Dates%19. IT/Effective Dates%19
  3. A statement always begins with the COBOL verb. Various Verbs in COBOL 1. Input / Output Verbs These verbs are used to get data from the user i.e input and shows the output of the COBOL program. Two verbs are used for this process: i. Accept Verb. Accept verb is used to get the data like date, time and day from the user or operating system
  4. In the COBOL view of the file, key-1 and key-2 overlap. But the requirements of XFD storage force the same data (known to COBOL as field-b) to be physically represented twice in the XFD. Any updates to the data from any ACUCOBOL-GT program will correctly update both fields. Updates from outside of ACUCOBOL-GT carry no such guarantee
  5. DIRECT FILE USED AS OUTPUT. A direct file was used as an output file. Change the program so that it does not use a direct file declaration. 22. INPUT FILE HAS VARIABLE LENGTH RECORDS. A variable record length file was used as an input file

In COBOL, the IF verb is used to test the conditions and the facilities in COBOL and to compare them with other languages. During validation routines, the programmer might wish to test if certain fields contain either only alphabetic characters or only numeric characters Program Analysis The program asks the user to input the names of the two files to compare. It will then open the files in read only mode and reads one line at a time from each file and compares them after stripping off any trailing whitespaces, which means we are ignoring new-line and spaces at the end of the line
