How to read line x from file. (and put it into a variable)

subject says all, if I have a text file - how can I read a given line from the file?

You must convert your text file in csv after you can read it with ui vision

actually . I discovered that CSVReadArray handles is as-is.
fwiw: no lines contain delimiters or space - and it is handles as a one-column array just fine.
