Crystal Reports中的 chr（13）和 chr（10）有什么区别？
What is the difference between chr(13) and chr(10) in Crystal Reports?
我知道 chr（13）被用作换行符。但是我们的报告之一使用以下行：
I know chr(13) is used as a line break. But one of our reports uses this line:
{Address1} + chr(13) + chr(10) + {Address2}
推荐答案
Chr（10）是换行符， Chr（13）是回车符。
Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.
如果您仅使用一个或另一个，您可能不会注意到它们的区别，但是您可能会发现自己处于输出状态不能正确显示一个或另一个。因此，将两者同时包含是更安全的。
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.
从历史上看，换行符会向下移动一行，但不会返回到第1列：
Historically, Line Feed would move down a line but not return to column 1:
This
is
a
test.
类似的回车将返回第1列，但不下移一行：
Similarly Carriage Return would return to column 1 but not move down a line:
This
is
a
test.
将此内容粘贴到文本编辑器中，然后选择显示所有字符，您将看到每行末尾都有两个字符。安全胜过遗憾。
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.
