COBOL REDEFINES Clause IN COBOL Explanation With Example in COBOL

2010-10-08T03:31:00.000-07:00

REDEFINES Clause IN COBOL Sometime two or more different variables defined in a program are not in use simultaneously. Their memory can be then saved by sharing the same location for all such variables which will not be used simultaneously. For this we can use redefine verb in cobol. The redefine verb.Using redefine the same memory location can be used for different variables, but the care of

COBOL COMP SYNC - What is COMP SYNC in COBOL?

2010-10-08T03:28:00.000-07:00

SYNC Keyword is used in COBOL to align the data(storage-area) to a Word-Boundary(Any address which is a multiple of 4). This is because, on Mainframes reading data from a word-boundary is computationally efficient.

COBOL INDEX, COBOL Sub-script - What is the difference between Index and Sub-script?

2010-10-08T03:22:00.000-07:00

Subscript is the slot-no. or position in the table. Index is the displacement (in no of bytes)/actual address from the beginning of the array. Indexes are much faster than subscripts. Subscripts have to be converted internally to the address. For example, 01 WS-TABLE. 05 WS-NAME OCCURS 5 TIMES PIC X(10). -----------------------

IS NUMERIC clause IN COBOL IS NUMERIC CLAUSE

2010-10-08T02:23:00.000-07:00

IS NUMERIC is used to check if the data is numeric or not. IS NUMERIC clause IN COBOL EXAMPLE 01 WS-TEXT PIC X(05). MOVE '15623' TO WS-TEXT. IF WS-TEXT IS NUMERIC DISPLAY 'NUMBER' ELSE DISPLAY 'TEXTUAL CHARACTERS’ END-IF. Output: NUMBER MOVE 'HE123' TO WS-TEXT IF

LEVEL 66 In COBOL : What is level 66 used for ?

2010-10-08T00:25:00.000-07:00

Level-66 Data-item is used for RENAMES Clause. RENAMES clause is used to regroup(Re-arrange), club together existing fields under a new name. 01 RECORDS. 05 GROUP-A. 10 FIELD-1 PIC 9(02). 10 FIELD-2 PIC 9(02). 05 GROUP-B. 10 FIELD-3 PIC 9(02). 10 FIELD-4 PIC 9(02). 66

HIGH-VALUES Clause in COBOL And LOW-VALUES Clause in COBOL - What are HIGH-VALUES and LOW-VALUES in COBOL?

2010-10-08T00:23:00.000-07:00

How does the Mainframe Computer store data and information? Every character or alphabet is represented as a unique 8-bit pattern of 0s and 1s. For example, A is stored as 1100 0001 or X'C1' in hex. B is stored as 1100 0010 or X'C2' in Hex. Similarly, the LOW-VALUE character is stored as 0000 0000 or X'00' in Hex. The HIGH-VALUE Character is stored as 1111 1111 or X'FF' in Hex. Understand, that

INDEX in COBOL : How to Define INDEX in Working-Storage Section ?

2010-10-08T00:20:00.000-07:00

01 WS-I USAGE IS INDEXThis is a valid working-storage definition of an Index.

EXIT PROGRAM Clause in COBOL

2010-10-08T00:19:00.000-07:00

EXIT PROGRAM only works in sub-programs, and transfers control to the calling Program. If used in the Main Driver Program, it causes 4038 Abend.

GO BACK Clause in COBOL

2010-10-08T00:18:00.002-07:00

STOP RUN Clause in Cobol

2010-10-08T00:18:00.001-07:00

STOP RUN terminates the entire run-unit – the Main Driver Program along with all its sub-programs. GO BACK returns the control back to the calling program.

What is the difference between STOP RUN, GO BACK and EXIT PROGRAM?

2010-10-08T00:17:00.000-07:00

STOP RUN terminates the entire run-unit – the Main Driver Program along with all its sub-programs. GO BACK returns the control back to the calling program. GO BACK when used the Main Driver Program, returns the control back to the OS. EXIT PROGRAM only works in sub-programs, and transfers control to the calling Program. If used in the Main Driver Program, it causes 4038 Abend.

Can you pass an Index to another COBOL Program, via LINKAGE SECTION?

2010-10-08T00:15:00.000-07:00

No, an INDEX is not a Working-storage area. It is maintained by the System. You can only send the data which is in Working-storage areas(Rough-work area) or in File Input-Output Areas to a COBOL Program. You can pass a Subscript to another COBOL Program.

88-Level In Cobol : What is 88-Level used for?

2010-10-08T00:05:00.000-07:00

Used for assigning labels to data-values that a COBOL-Variable can take. Very useful in detecting special-conditions. They work like flags or switches. 01 TEMPERATURE PIC 9(03). 88 HIGH-TEMPERATURE VALUES 75 THRU 100. 88 MEDIUM-TEMPERATURE VALUES 50 THRU 74. 88 LOW-TEMPERATURE VALUES 32 THRU 49.

COBOL coding sheet

2010-10-08T00:01:00.000-07:00

Almost all COBOL compilers treat a line of COBOL code as if it contained two distinct areas. These are -AREA A- Between Column 8 to 11-Division, Section, Paragraphnames, FD entries & 01 level entries must start in Area A AREA B- Between Column 12 to 72- All Sentences & Statements start in Area B

COBOL coding rules

Each line is considered to be made up of 80 columns.Columns 1 to 6 are reserved for line numbers.Column 7 is an indicator column and has special meaning to the compiler. Asterisk ( * ) indicates comments Hyphen ( -) indicates continuation Slash ( / ) indicates form feedColumns 8 to 11 are called Area A. All COBOL DIVISIONs, SECTIONs, paragraphs and some special entries must begin in Area
