``` if trueOrFalse then statements [else if trueOrFalse then statements] [else statements] end if ```
The multiple-statement if structure tests the specified condition and executes one or more statements if the condition is true. You use the optional else if or else form to run alternative blocks of code in case the condition following if is false.

Because each part of a complex if structure may contain more than one statement, you must have an end if statement at the end of the structure.
