3.13 Developing Procedures

Procedures are a way to organize code so that a set of instructions can be reused whenever needed. Instead of rewriting the same logic multiple times, a procedure groups those steps under a single name. This makes programs easier to read, easier to debug, and easier to modify. A procedure can take inputs, called parameters, and may produce an output using RETURN. When a procedure is called, the program executes the steps inside it using the given inputs.
