How do you identify a static call and dynamic call in COBOL?

how can i identify a CALL statement is DYNCMIC or STATIC? Quote: When you use a CALL literal statement in a program that is compiled using the DYNAM and the NODLL compiler options, or when you use the CALL identifier statement in a program that is compiled using the NODLL compiler option, a dynamic call occurs.

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 static and dynamic call?

A call to the subprogram at the time to compilation. Static call uses more CPU time, memory required is large. 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. Degrades performance.

What is static linking and dynamic linking in COBOL?

A statically linked program is a program or subprogram that is held in object form in an executable object file. It cannot be referenced from other executable files. Dynamic loading (no linking) The COBOL Run-time system (RTS) enables you to run a dynamically loadable program without needing to link it first.

What is a static call?

When you use the CALL literal statement in a program that is compiled using the NODYNAM and NODLL compiler options, a static call occurs. With these options, all CALL literal calls are handled as static calls. With static calls statement, the COBOL program and all called programs are part of the same program object.

How do you change a static call to a dynamic call in COBOL?

For COBOL-DB2 programs you can easily convert static calls to dynamic without even modifying your code. Use DYNAM compiler option to compile your cobol code. It will itself covert all the static call into dynamic calls. This way you could be sure of dynamic calls if your code compiles successfully.

Why static call is faster than dynamic call in COBOL?

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 dynamic call in COBOL?

Dynamic CALLs In the dynamic CALL, the called COBOL subprogram is not link-edited with the main program, but is instead link-edited into a separate load module, and, at run time, is loaded only when it is called.

What is a dynamic call?

Dynamic CALLs When a dynamic CALL statement calls a subprogram that is not resident in storage, the subprogram is loaded from secondary storage into the region or partition containing the main program and a branch to the subprogram is performed.

What is the difference between static call and dynamic call in COBOL?

COBOL – STATIC CALL vs DYNAMIC CALL – Which one is preferred when? Static or Dynamic call is identified by CALL statement. For DYNAMIC call we use working storage variable to store program name and use that variable in the CALL statement.

What are static calls in C++?

Calls made in such configurations is referred to as static calls. This kind of call occupies more memory as one executable load contains both calling and called program When calling program (main program) is compiled using DYNAM or NODLL compiler option, recompilation of calling program is not needed to accommodate the modifications of sub-program

What is the difference between static call and sub-call?

In a static call only one load will be available.The called subprogram must be link-edited with the calling program to form a single load module . If there is any change to sub program then we have to compile main program also.

What is a static call in nodynam?

When calling program (main program) is compiled using NODYNAM compiler option (default), recompilation of calling program is needed to accommodate any modification of sub-program Calls made in such configurations is referred to as static calls. This kind of call occupies more memory as one executable load contains both calling and called program
