- 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.
