Constant is data whose value cannot be changed during the runtime. Every con-

stant is declared under unique name which must be a valid identifier. It is a good

practice to write constant names in uppercase.

In mikroBasic, constants have to be of simple data type (no arrays or strings are

allowed).

Example of constant declaration:

const MAXVALUE = 237

Constants can be used in any legal expression, but they cannot be assigned a new

value. Therefore, they cannot appear on the left side of the assignment operator.

If you frequently use the same value throughout the program and its value is fixed,

you should declare it a constant (for example, maximum number allowed is 1000).

This is a good practice since the value can be changed simply by modifying the

declaration, instead of going trough the entire program and adjusting each instance

manually. As simple as this:

const MAX = 1000

It is important to understand why constants should be used and how this affects

the MCU. Using a constant in a program consumes no RAM memory. This is very

important due to the limited RAM space (PIC16F877 has 368 locations/bytes).
