问题 What is the difference between chr(13) and chr(10) in Crystal Reports? I know chr(13) is used as a line break. But one of our reports uses this line: {Address1} + chr(13) + chr(10) + {Address2} 回答1: Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character. You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.
