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 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.
