Variables
A program is a group of commands and instructions that tell the computer to carry
out a task. In Scratch, a program is called a script. A script is made up of a number
of blocks. So, the blocks are the commands or instructions that we give to the sprite
to perform a task.
All the numbers, text, date, 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 its value is not fixed
and can change. For example, in the block, the variable has a value 10 by
default. You can modify this value according to your script.
Types of Variables
Variables can store numbers as well as letters. A variable that stores numbers is
called a numeric variable. These numbers are used in calculations. Examples are 48,
–986, 12345, etc.
