Which term refers to additional routines that can be called within the MainRoutine?

The term that refers to additional routines that can be called within the MainRoutine is "Subroutines." Subroutines are segments of code designed to perform specific tasks and can be invoked from various points within a program, including the main routine. They help in structuring code into manageable sections, allowing for easier maintenance and reusability. This modular approach promotes cleaner programming, as the subroutine can be tested and modified independently of the main routine.

In the context of a programmable controller system, subroutines are particularly useful for breaking down complex tasks into smaller, more manageable parts. By employing subroutines, programmers can encapsulate functionality that can be reused across different applications or throughout the same program.

Other terms, while related, do not specifically describe the concept of additional routines that can be called from a main routine in the same way. Functions often refer to routines that return values and may be used interchangeably with subroutines in some programming contexts. Modules generally refer to larger structural components or libraries of related functions and subroutines, rather than individual additional routines. Processes imply a series of actions or steps needed to complete specific tasks, which may encompass broader functionalities beyond just the subroutine context.
