How do you call a subroutine in COBOL?

How do you call a subroutine in COBOL?

Following is the syntax of calling subroutine by reference: CALL sub-prog-name USING variable-1, variable-2. Following example is the MAIN calling program and UTIL is the called program: IDENTIFICATION DIVISION.

How do you call in COBOL?

1. The Syntax of DYNAMIC Calls. Type 1: CALL ‘WS-SUB-PGM’
2. Simple Calls in COBOL. Simple Calls are calls without passing any value or arguments to the CALLED Programs.
3. Call By Reference. The CALLING Program sends the copy of the content of the parameters to the CALLED Program.
4. Call By Content.
5. Call By Value.

How do you call a module in COBOL?

Call Verb. Call verb is used to transfer the control from one program to another program. The program that contains the CALL verb is the Calling Program and the program being called is known as the Called Program. Calling program execution will halt until the called program finishes the execution.

Which is better static or dynamic call in COBOL?

Because a statically called program is link-edited into the same load module as the calling program, a static call is faster than a dynamic call. A static call is the preferred method if your application does not require the services of the dynamic call.

What is Dynam and Nodynam in COBOL?

DYNAM- If we give this compiler option, we need to give only dynamic calls and no static calls in COBOL program. NODYNAM – If we give this compiler option, we can give both static and dynamic calls in the COBOL program. Static CALLs.

What is difference between call by value and call by content in COBOL?

BY CONTENT means that the calling program is passing only the contents of the literal or identifier . BY VALUE means that the calling program is passing the value of the literal , or identifier , not a reference to the sending item. The called program can change the parameter in the called program.

What is static and dynamic call in COBOL with example?

A static call is specified withe a CALL LITERAL, and the program is compiled with COBOL NODYNAM option. A call to the subprogram at the time of exectution (run time) is called Dynamic call. Dynamic call uses less CPU time, memory required can be less. Caller and called programs are link edited as seperate load modules.

Which call is faster static or dynamic?

Because a statically called program is link-edited into the same program object as the calling program, a static call is faster than a dynamic call. A static call is the preferred method if your application does not require the services of the dynamic call.

What is the difference between rename and redefine in COBOL?

REDEFINES VS RENAMES: RENAMES clause is used for regrouping elementary data items and gives one name to it. REDEFINES clause allows you to use different data descriptions entries to describe the same memory area.

What is Ssrange and Nossrange in COBOL?

SSRANGE is a compiler option that handles the array overflow. SSRANGE also needs to be specified in COBOL programing language. These help in finding the subscript out of range. NOSSRANGE is a default option that doesn’t support any runtime error if the index or subscript runs out of range.
