Linked subroutine is an essential computer programming term, often abbreviated as "L-SUB." Its spelling is determined by the phonetic sounds of each individual letter in the term. Using the International Phonetic Alphabet (IPA), "linked subroutine" is pronounced as /lɪŋkt sʌbˈrutin/. The "l" starts the term with a crisp, sharp sound, followed by the short vowel sound of "i." The "k" is pronounced hard, while the "t" at the end is pronounced with a soft, ending sound.
A linked subroutine refers to a section of computer code that is designed to perform a specific task and is independent of the main program. It is called a "linked" subroutine because it is connected or linked to the rest of the program through a process called linking.
Linking is the process of combining different sections of code to create a single executable program. During this process, the linked subroutine is incorporated into the main program, allowing it to be called or executed whenever required.
A linked subroutine is often utilized to modularize a program, making it more manageable and efficient. It encapsulates a set of instructions that can be reused multiple times without having to rewrite the same code repeatedly. By separating specific functionality into subroutines, programs become more organized, easier to understand, and less prone to errors.
Moreover, a linked subroutine can be shared among different programs, making it a versatile and reusable component of software development. It can be created as a separate module or file that can be called from different programs when needed, promoting code reusability and reducing development time.
In summary, a linked subroutine is an independent section of code that is incorporated into the main program through linking. It enhances code organization, promotes reusability, and allows for efficient modular design in software development.
The etymology of the term "linked subroutine" can be understood by examining the origins and meanings of its individual components:
1. Linked: Connected or joined together.
Origin: From the verb "link", derived from the Old English word "hlencan", meaning "to join or fasten".
2. Subroutine: A sequence of program instructions performing a specific task, designed to be reusable within a larger program.
Origin: From the words "sub" (meaning "under" or "part of") and "routine" (referring to a set sequence of actions).
Therefore, the term "linked subroutine" refers to a reusable sequence of program instructions that is connected or joined together within a larger program. The term emphasizes the idea that the subroutine is effectively integrated or connected to the main program through linking mechanisms in computer programming.
