echo command

Hi, what I'd like to do is to get some input with read commands and then put them all inside a .txt file, each entry in a new line, to create something like a list. The printf command is not available, so I tried into the new line, it's all printed in the same first line. I'm using an ash shell that comes with my BusyBox v1.00-rc2 for ARM and this is the commands list:
