Difference between chr(13) and chr(10)

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.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.
