Difference Between GOBACK and STOP RUN in COBOL

STOP RUN and GOBACK are two commonly used terms in COBOL programming. GOBACK is a statement which refers to the logical end of a given program in COBOL. STOP RUN, on the other hand, will terminate the program on its own or if called by a COBOL program.

What will happen if you code go back instead of stop run in a standalone Cobol program?

A Stop run ends the unit of work and returns control to the operating system whereas GOBACK returns control to calling program. So if we code GO BACK instead of Stop Run, it will go in infinite loop.

What is the difference between continue and next sentence?

NEXT SENTENCE gives control to the verb following the next period. CONTINUE gives control to the next verb after the explicit scope terminator. It's safest to use CONTINUE rather than NEXT SENTENCE in COBOL II. ...

What does exit do in Cobol?

The EXIT PROGRAM statement specifies the end of a called program and returns control to the calling program. You can specify EXIT PROGRAM only in the procedure division of a program. EXIT PROGRAM must not be used in a declarative procedure in which the GLOBAL phrase is specified.

What is static and dynamic call in Cobol?

Static Call occurs when a program is compiled with the NODYNAM compiler option. A static called program is loaded into storage at compile time. Dynamic Call occurs when a program is compiled with the DYNAM and NODLL compiler option. A dynamic called program is loaded into storage at runtime.

How do you end a Cobol program?

STOP RUN is the last executable statement in the program which will returns the control back to OS. STOP RUN always coded in the main program. If STOP RUN coded in the sub program, the control will return to OS instead of returning to main program.

Which statement is used in Cobol to terminate the execution?

STOP RUN and GOBACK are two commonly used terms in COBOL programming. GOBACK is a statement which refers to the logical end of a given program in COBOL. STOP RUN, on the other hand, will terminate the program on its own or if called by a COBOL program.

What is the next sentence?

The NEXT SENTENCE statement transfers control to the next COBOL sentence, that is, following the next period. It does not transfer control to the logically next COBOL verb as occurs with the CONTINUE verb.

What is continue in Cobol?

Continue statement in COBOL, is used to transfer control implicitly within the paragraph or section. ... COBOL continue statement indicates that no executable instruction is present, and control will be transfer control to the next executable instruction after an explicit scope terminator (i.e. END-IF etc.).

What is scope terminator in Cobol?

A scope terminator is any COBOL verb that is either a) always conditional (IF, EVALUATE) or b) has a conditional clause (COMPUTE, PERFORM, READ) that will have a matching scope terminator. They always begin with END- and are completed by including the reserved word that they are terminating.

What is 77 level used for in Cobol?

77 level variable is used for independent data item and it has no other sub level declaration. Level 77 can't be subdivided to another item nor they can't be sub divided by themselves. Level 77 reduce usage of memory during runtime with no extra byte being used hence it has no chance to add elementary items.

What is level 88 in Cobol?

Level 88s are used to assign names to values at execution time. Thus, a condition-name is not the name of an item, but rather the name of a value. A level 88 doesn't reserve any storage area. Each level 88 must be associated with a data item and must immediately follow that item in the Data Division.

How do you evaluate in Cobol?

COBOL EVALUATE statement

1. EVALUATE statement is used for conditional processing in COBOL.
2. It performs the various set of tasks- If multiple conditions need to be checked then EVALUATE is a better than IF-ELSE. ...
3. EVALUATE cond-for-evaluate [ALSO] cond-for-evaluate [ALSO] … ...
4. EVALUATE TRUE. ...
5. EVALUATE LEVEL-88-COND.
