A question on the procedure of the program

[karen8169]

I use the same data, but the result is different. Who can tell me what wrong is.

Instead of attaching files, why not make it easier for the people whose help you are requesting?  You can use the little Insert SAS Code  or Insert Code icon to insert your sas programs.  Then we could all see it without the attendant risk (and annoyance) of having to download.

As to your question.  Please identify some differences (i.e. actual values) that you did not expect.  And show us the sas log that came from running your programs.

Your programs don' t run properly. The data contains tabs and is not read as given.

How to solve the problem? It can't read .csv well. Should I seperate each datum with a comma?

A correctly structured CSV should have commas. CSV -> Comma Separated Values

Start with the errors in the order they appear, otherwise they propagate throughout your program. 

If your file isn't a CSV, what is the delimiter?

Separate however you want. Just ensure that the program supplied can be executed.

Paste using the appropriate methods (see post by @mkeintz)  and then run the text that you have pasted after copying it from the page.
