@tomleslie 

Thank you, I'm taking a look! There are many other commands I haven't used before!

@Thomas Richard 

I found that the version I intalled is Maple 11, and the "getdata" command was introduced in Maple 15. Now I have installed the version 15 already and trying this command. Thanks for you responses.
I still want to know how to output the data as format:

i j f(i,j)
0 0 0
1 0 1
2 0 2
... ... ...

Another question, can maple enter the words in a text like"hello"?
