if (single-statement)

if trueOrFalse then statements ¬
   [else statements]

if trueOrFalse
then statements
[else if trueOrFalse
then statements]
[else statements]

The single-statement if structure tests for a condition and executes one statement if the condition is true. You use the optional else if or else form to run other blocks of code in case the condition following if is false.

Because each part of a simple if structure is limited to one statement, you don't need an end if statement.

You can send a one-line if structure from the Message box.

Examples

if it is empty then exit myHandler

ask file "Save information to file:"
if it is empty then exit myHandler 
else saveFile it

ask file "Save information to file:"
if it is empty 
then exit myHandler 
else saveFile it

Placeholders
