Let's Revisit
Prime (Ver. 2.2)-V • In Scratch, a program is called a Script.
• Hat blocks always come at the top of a script as they start a script.
• Stack blocks perform the main commands.
• Boolean blocks are the conditional blocks which return the values “true” or “false”
or the numbers “0” or “1”.
• Reporter blocks can hold values, which consist of numbers or strings.
88 • C blocks are loop blocks which check if a condition is true in the blocks within the
loop.
• The blocks that end scripts are known as CAP blocks.
• The sensing blocks in Scratch sense the input from the keyboard or the mouse at
the time of execution of a script.
• We store data in the computer memory so that we can get information from it
later. This data is stored in variables.
• A variable that stores numbers is called a numeric variable.
• A variable that stores letters in the form of strings or characters is called a
string variable.
