What is the programming term for a line of code that allows you to refer to an entire series of steps or commands?

The term that best describes a line of code that allows you to refer to an entire series of steps or commands is "Function." A function is a block of code designed to perform a specific task. It can take inputs, known as parameters, and will often return a value after executing its designated series of steps. This makes functions a fundamental building block in programming, enabling code reusability and better organization.

In addition, while "method" can also be used in object-oriented programming to refer to functions associated with an object's data, it’s more context-specific. A "procedure" typically refers to a type of function that performs operations but does not return a value, which makes it less fitting when discussing general programming terms. "Object," on the other hand, refers to an instance of a class containing both data and methods, rather than specific operations or commands.

Thus, when considering the broader programming context, a function is the most appropriate term for a line of code encapsulating a series of steps or commands.
