All the numbers, text, dates, or pictures that we use in a program are called data.
We store this data in the computer memory so that we can get information from it
later. This data is stored in variables. It is called a variable because it does not have

a fixed value, its value changes. For example, in the move block, the variable has a
value 10 by default. You can modify this value according to your script.

Types of Variables

There are two types of variables. They are as follows:

Global Variables

If a variable is created to be used and modified by all the Sprites, then it is known as

a global variable. A Global variable can be created on any Sprite but its value can be
accessed or modified by other Sprites used in the project.

Local Variables

If a variable is created to be used and modified by a single Sprite only, then it is
known as a local variable. Local variables can only be accessed or modified from the
Sprite where it was created.
