Every script is a series of statements. Each statement consists of a command and may contain additional information needed to perform the command.

Statements can be simple, such as this one-line command:

tell application "Finder" to activate

Statements are usually complex, containing more than one statement. The following example includes several statements.

Show me a compound statement.

When you run a script, each statement is executed in order. However, some statements can control the order in which statements are executed, as in the next example.

Show me a control statement.

This example includes two control statements:

•	The Tell statement controls which object receives the other statements. In this case, the Finder application is the object.
•	The If statement controls whether or not the second Set command is executed. It's only executed if it's true that the variable "item_comments" is empty.
