Example
Say you want a user to add a descriptive paragraph about the novel he or she has just reviewed. If the description is brief, you’d like to keep it in the same paragraph as the lead-in sentence. However, if the user has much to say about the novel, you would like to start a new paragraph.
To perform this action, your script would appear as follows:
«IF LENGTH( Plot Description ) <= 150»
The novel's plot description is as follows: «Plot Description»
«ELSE»
The novel's plot description is as follows:
«Plot Description»
«END IF»
