How to create text file like this?

[ha noi]

I want to create text file like attached file. I thought to create 2 text file: First text file make the headers ( Position, value 0,value 1....) , Second file make the table of data. Then combine them to be third text file. Someone can post other solutions?

Hi ha noi,

you don't need 2 intermediate textfiles!
Just write the header line first, then attach lines containing values...
