Modularisation. It could also be called refactoring, where large and complex functions are split into several simpler functions, making code easier to read. Refactoring can also help to reduce code duplication.
Function modules are procedures that are defined in special ABAP programs only, so-called function groups, but can be called from all ABAP programs. Function modules allow you to encapsulate and reuse global functions in the SAP System. They are managed in a central function library. The SAP System contains several predefined functions modules that can be called from any ABAP program. Function modules also play an important role during updating and in interaction between different SAP systems, or between SAP systems and remote systems through remote communications.
When a module is called, the computer jumps to that module and executes the statement in the module's body. Then, when the end of the module is reached, the computer jumps back to the part of the program that called the module, and the program resumes execution at that point.End
A function. You can have a function that returns but doesn't return a value with it.
Functions hold code, which means anything that happens within a function can be "called" later on. Allowing the programmer to save time, and ensuring he doesn't have to re-write code. Example: Instead of writing "Hello" 10 times, I made a function that said print("hello") 5 times, then "Called" the function twice. def helloFiveTimes(): print("Hello") print("Hello") print("Hello") print("Hello") print("Hello") return helloFiveTimes() helloFiveTimes()
In C and C++, as well as in many (all?) languages, a function can be called from more than one place in a program. That's the purpose of functions - to encapsulate pieces of code that are needed in more than one place in the program.

In SAP ABAP (Advanced Business Application Programming), a Function Module (FM) is a reusable unit of code that performs a specific task or set of tasks. Function Modules are similar to procedures or functions in other programming languages and are used for modularizing and organizing code in SAP systems. Here are the key uses and features of Function Modules in SAP ABAP: Reusability: One of the primary purposes of Function Modules is to encapsulate a specific functionality, making it reusable across different programs, reports, or modules within the SAP system. This promotes code reusability and modular programming. Modularity: Function Modules help in breaking down complex programs into smaller, manageable units. Each Function Module focuses on a specific task, contributing to a modular and structured codebase. Encapsulation: Function Modules encapsulate a set of related operations and data, providing a clear interface for other programs to call. This encapsulation enhances code maintainability and reduces dependencies. Abstraction: Function Modules abstract the underlying implementation details, allowing other programs to use the module's functionality without needing to know the internal workings. This abstraction promotes a separation of concerns. Input and Output Parameters: Function Modules can accept input parameters to customize their behavior. They also return output parameters, allowing them to communicate results or data back to the calling program. Remote Function Call (RFC): Function Modules can be marked for Remote Function Call (RFC), enabling them to be called from external systems or programs. This is useful for integrating SAP systems with other systems or applications. Global Data Sharing: Function Modules can utilize global data, making it possible to share data between different programs or function modules within the same SAP session. Standard SAP Functionalities: SAP provides a vast repository of standard Function Modules that encapsulate common SAP functionalities. Developers can leverage these standard FMs for various purposes without having to develop the functionality from scratch. Enhancements and BAdIs: Function Modules are often used in conjunction with enhancement techniques like User Exits and Business Add-Ins (BAdIs). They can be called to execute custom logic at specific points within standard SAP processes. Testing and Debugging: Function Modules can be tested and debugged independently of the calling programs, simplifying the development and troubleshooting process. Event Handling: Function Modules are used for handling events, especially in the context of workflow or event-driven programming. They can be triggered in response to specific system events. In summary, SAP ABAP Function Modules offer a powerful mechanism for organizing, reusing, and abstracting code in SAP systems. They play a crucial role in achieving modular and maintainable codebases within the SAP environment.
It is the first function that gets called when the program is executed.
A function is a subprogram written in VHDL. This program can be called and used in other programs.
function is a self contained block or sub program of two or more statements which performs a special task when called.
function is a self contained block or sub program of two or more statements which performs a special task when called.
A function. You can have a function that returns but doesn't return a value with it.
In the context of a macro or program, the values of the arguments of the function (variables) are substituted into the function and it is evaluated. The result is returned.
There are a number of different names. They are usually in the form of SIMMs (Single Inline Memory Modules), and people often call them just memory modules. Some also call them memory cards or memory sticks. They may go by other names based on the exact chips and how they are wired, such as DDR, DDR2, DDR3, and so on.They are sometimes called MultiChip Modules. When their sole function is RAM they can be called Memory Modules.Sometimes they are identified by the type of connector: SIMM, DIMM, UDIMM, SODIMM, etc.Memory Modules (memory card)
