Hi,

Could you please answer for these questions.

1. Difference between EXIT & EXIT-PROGRAM?

2. Difference between EXIT & GOBACK?

3. What will happen if i code GOBACK & STOP RUN in same program?

4. I have a following structure.

01 A PIC X(100) VALUE 'NAME SALARY NAME SALARY NAME SALARY
...........'
Like that 100 characters. Now i want to display the above one is as follows.

NAME SALARY

NAME SALARY
.
.
.
NAME SALARY.

Please tell me the code for this.

Please let me know the answers for above questions.

Thanks,
Sunny.

hy sunnybunny,

1. EXIT means EXIT from a paragraph you just performed,
EXIT-PROGRAM you finish the program.

2. GOBACK you code normally for subroutines,
it is like EXIT-PROGARM but returns to the caller.

3. EXIT-PROGRAM is like STOP-RUN...
finishing the program

4. 01 A PIC X(100) VALUE 'NAME SALARY NAME SALARY NAME SALARY...
i assume NAME and SALARY alre always from different length.
if so, then STRING/UNSTRING this stuff. if the sizes for NAME and SALARY
are from the same length, i.e. NAME PIC X(20), SALARY PIC 9(05),
then you can redefine your variable with an array, and display its value
in a loop....

Hi Everybody,

Just i need to add some more info ..

EXIT-PROGRAM-------> No action will be taken if you use it in your main program ..but if you use it in any sub program then the control will transfer to calling program.

GOBACK---------> When it is used in the main program, stops the program when executed and control will be returned to OS....where is when it is used in subprogram, control will be returned to the calling program..

STOP RUN ---> When it is executed either in main program or sub program, program execution will be stopped and the control will be returned to OS.

Please let me know if i'm wrong any where..

Thanks and Regards,
RS

Hi,

Just wanted to add a point regarding this.
I saw the replies and found one of the answers as
"EXIT means EXIT from a paragraph you just performed"

As far as I know, it doesnt do that !!
A paragraph identifies that it is done when it encounters a new PARA AND NOT when it encounters exit. So basically EXIT does nothing and is just a way of coding.

Any corrections and always welcome.

EXIT statement does nothing. It never exists from a paragraph. A paragraph ends when we reach another para or section.

As every peragraph needs to have at least one statement, we use EXIT as its more meaningful.

I hope this makes it clear that why EXIT is used and what it does.

Hi,

->STOP RUN is the last executable statement of the main program ( or sub program ). It returns control back to OS.

->GOBACK can be coded in main program as well as sub-program as the last statement. It just gives the control back from where it received the control.

->EXIT PROGRAM is the last executable statement of sub-program. It returns control back to main program. However in main program the EXIT PROGRAM will act as a NULL statement and execution will continue from next impertative statement.

->EXIT acts as a NULL statement and does nothing. If used it should be the only statement in the para.

Thanks.
