This document discusses the differences between functions and procedures in programming. It states that functions and procedures are blocks of code that perform specific tasks and can be reused. The key differences are that functions always return a single value, while procedures can return multiple outputs or none at all. The document provides examples of how to define a function with parameters and return types, and how to call a defined function. It also explains how to define procedures with various input and output parameters.

2. INTRODUCTION
• Functions and procedures are known as applets
• However, from an application point of view, there is a fundamental difference between
processes, functions or procedures: while the former aims to immediate use in the main
code, the other aim use in libraries, its purpose is to store common pieces of code, so it
can be reused or shared with other projects.
• In programming procedures and functions they are also known by the name
routines, subroutines or subprograms. They are blocks of instructions that perform tasks
specific. The routines are declared only once but can be used by calls,
Sometimes all you want in a program. A routine is independent from the rest of
program so in principle facilitates the design, monitoring and correcting a
program. They can also be stored in collections called independent bookstores
units, allowing them to be used in any program

3. FUNCTIONS
• A function is a sequential code section.
• Its purpose is to create code to deal with common design problems,
such as:
Data type conversion,
Logical operations,
Arithmetic and
New operators and attributes.
• The functions are similar to the processes, since they can be used in
both statements (IF, WAIT, CASE, LOOP) except WAIT.
• Important. The function will always return a value, while procedures
do not.

4. FUNCTIONS
• To make and use a function, two parts are necessary: the same
function (function body) and the call to the function. Its syntax
is as follows:
• Example:
Name: f1, three parameters: a,b and c, a and b are constants.

5. FUNCTIONS EXAMPLE
• is not necessary to place the constant word because the system
defaults, while c is a signal
• a y b they are integer, whereas c is the vector type.
• Called:
Video

6. PROCEDURES
• A procedure is very similar to a function and has the same purpose.
However, a method may return more than one output value.
• Procedure body
• Here specific inputs and outputs
• A procedure can have any number of input parameters, output or
input-output, which in turn can be signs, variables or constants.
