COBOL - SYNTAX-SYNTAX ON SEQUENTIAL FILE

Hello my friends IT knowledge lover. You are on my blog at “We Are Knowledge”.in here you will getting many IT knowledge and general knowledge. In this blog to be found IT knowledge from “Web programming” like as : HTML, PHP, JAVASCRIPT until “Dekstop programing” like as : cobol, visual basic 6, c++. And in here you also can find article about graphic design using “Adobe Photoshop”..

Like this article discuss about COBOL. You know program language COBOL ? if you do not know, let’s do read my article.. and topic of our discussion this time is “SYNTAX-SYNTAX 

ON SEQUENTIAL FILE”. You will know ??? C’ mon to read this article… have fun for read it friends..

In COBOL to be found “division”, that is ::

1. Identification Division

2. Environment Division

3. Data Division

4. Procedure Division

But for SEQUENTIAL FILE just discuss point 2 (two) until 4 (four)..

1. ENVIRONMENT DIVISION

Example ::

INPUT-OUTPUT SECTION.

FILE-CONTROL

SELECT name_of_file ASSIGN TO { DISK PRINTER }

[ORGANIZATION IS [LINE] SEQUENTIAL]

ACCESS MODE IS SEQUENTIAL.

FILE STATUS IS name_of_data.

Logic ::

SELECT

>> You should write this first

ASSIGN

>> choose the form of files that will be used, disk or print files.

FILE STATUS

>> This syntax is used to indicate (to know) the type of error that occurred

2. DATA DIVISION

In syntax on data division the equation, ie :

LABEL RECORD IS OMMITED == LABEL RECORDS ARE OMMITED

LABEL RECORD IS STANDARD == LABEL RECORDS ARE STANDARD

LABEL RECORD IS OMMITED

>> This syntax is used to print files that do not have a label

LABEL RECORD IS STANDARD

>> This syntax is used to print a file that has the label

3. PROCEDURE DIVISION

OPEN

>> this syntax for openning your file to be accessed.

CLOSE

>> this syntax for clossing your file which has been used, because if you not close, possibility your file be broken

WRITE

>> use this syntax if you want to display the output to a printer or to record data to a file that you designated.

REWRITE

>> This syntax is used to re-record the files you've recorded earlier

READ

>> this syntax used for reading in your file

Ok. just it..

I hope you like..

see you later friends...
