Scratch Syntax: Part 1CMP

StatementsIn programming, a statement is simply a directive that tells the computer to do something. Think of it as a command or an instruction. In Scratch, any block whose label reads like a command is a statement.

ConditionsIn programming, a condition is something that must be true in order for something to happen. A condition is thus said to "evaluate to true" or "evaluate to false." In Scratch, any block whose label says "if," "when," or "until" is a sort of conditional construct.

ConditionsIf Construct: Instruct a sprite to say hello only if, say, the user has depressed the mouse button:When Construct: Instruct a sprite to do something when an event occurs:

LoopsIn programming, a loop can induce multiple executions of statements. In Scratch, any block whose label begins with "forever" or "repeat" is a looping construct.
