A variable is like a box that can hold one value at a time, such as one word, one costume, or one list (which can contain many things). You can look at what's inside as many times as you want.

A local variable can be set or used only in the environment in which it is defined. This term includes inputs to procedures and variables created by the for or script variables block.

A predicate is a hexagon-shaped reporter that asks a true/false question.

Predicates report a Boolean value either true or false.

The if and if-else blocks are called conditionals because they control the code based on a true-or-false condition.

A global variable is a variable that is usable by all scripts in the program.

Setting the starting value of a variable is known as initializing the variable

The position number is called the index of the item in the list.
