When you do some changes in any object (e.g. Cobol, Copy book or table or proc or card). Due to that change how many elements are implected? This is called Implecte Analysis.

COMP Usage is used for data items of numeric type. There are 4 types of COMP usage. 
1.COMP : Used only for integers.Either half word or full word . 
2.COMP -1 :Used for floating points.Internal representation is hexa decimal.full word is used.No PIC Clause . 
3.COMP -2 : Similar to COMP-1.Only difference is double word(8 bytes )is used 
4.COMP -3 :Interenal representation is decimal.Each character is assinged to half byte.The sign bit is assinged to right most bit. The no.of bytes required for n characters is (n/2) + 1 (rounding down)

The DISP=SHR in JCL means that the file is already existing and that it is not exclusively locked for your own use. Other user can still access this file. And the EXTEND in the COBOL program means that, when you open the file, the record pointer will be positioned on the last row of the record and every insert you'll make will be appended on the last position of the file.

In Cobol there are 4 divisions.

1. Identification division or ID division
In this no setions are there. It has 5 paragraphs.
a. Progaram-id. programname
b. Author
c. Writen-date
d. Compiled-date
e. Installer

2. Environment Division
Under this there are two sub-sections
a. Configuration-section.
     Source compter.
     Object computer.
b. Input-Output section.
     File control.
     IO control.

3. Data Division
File-section.
Working-storage section.
Linkage section.
Report section.
Screen section.

4. Procedure Division

saurabh bandyopadhyay

• May 25th, 2012

There is another section in Data division; named as LOCAL-STORAGE SECTION.

For a recursive cobol program, you need to use that section to hold the current values of each variable while the program run.

In the case of static call the mainprogram and subpgms r loaded into the mainmemory initially.in the case of dynamic call only the mainpgm is loaded first and the subpgm is loaded only when a call to it is made.so the memory utilization is good in dynamic call.

Copy - Expand the copybook statements during compilation time.

Include - Expand the copybook statements during pre-compilation time. Usually for DELGENS we use INCLUDE as DCLGEN statements needed during pre-compilation process.

surya

• Dec 31st, 2015

Copy will be used in the cobol compile process and Include will be used during the Db2 precompile process. So we include a Dclgen. We cannot copy a dclgen..If so the program will fail the compilation.We can include a copybook too.

NEXT SENTENCE gives control to the verb following the next period. CONTINUE gives control to the next verb after the explicit scope terminator. (This is not one of COBOL II's finer implementations). It's safest to use CONTINUE rather than NEXT SENTENCE in COBOL II.

Continue pushes the control to Add +1 to Input-count. Say if Input-count was 0 then the value will be iterated to 1

Next sentence will never add +1 to Input-count it will bypass the command. Say if Input-count was 0 then the value will remain same.

When NEXT SENTENCE is coded, Program will not add +1 to INPUT-COUNT.
When CONTINUE is coded, +1 will be added to INPUT-COUNT.
