Dear Shawn, Please forgive me for my poor English explanations of my question, there are three files, file 1, file 2 and file3.
File 1: a b c d e f j p k file 2: x y z q w e n a s d file 3: 1 2 3 3 4 5 8 9 2 1 I read file 1 to $a, file 2 to $b and file 3 to $c, I want to product file 4, it contain file 1 , file 2 and file 3. File 4: a b c x y z 1 2 3 d e f q w e n 3 4 5 j p k a s d 8 9 2 1 and put file 4 into $X. I don’t know whether I explain my question clearly, anyway, thank you very much.

If you're asking about output format, you can either use printf, look at one of the grid modules, or use perltex (or there's probably a docbook or mathml module or two but I haven't looked).
