How to change line when making Files with Expression2

[Gascan]

Hi there I've been trying out the file functions in expression 2 and i wanted to know how to change lines. right now I've been using fileAppend(S,S) but that just made it write all the information in one line. I've been looking on the site, but i couldn't find anything :S Please help.
Thank you

I don't know if these all work, newline should work at least.

\a bell
\b back space
\f form feed
\n newline
\r carriage return
\t horizontal tab
\v vertical tab
\\ backslash
\" double quote
\' single quote
\[ left square bracket
\] right square bracket

Edit to be clear:
"HP\nSauce" makes

HP
Sauce

You use an index. Say you wrote this to your file:

1|Pie /n
2|Cake /n
3|Hamburgers /n

and you wanted "Cake", you would simply read until you hit "2|", read until you hit toChar("13").

I never actually tried it, but if you use newline, you should be able to use Lines = fileRead(File):explode(toChar(13)).

err...i dont understand exactly what you telling me.. i know it uses a index (line1,line2,line3,.....)

my code should look like this:

String = fileRead("testfile.txt") # only want to read line 2 of the testfile.txt

[Timomo]

ok... i think for this we need a new function.. like

StringLine = fileRead(filename, line)

[Whosdr]

Nah.
I think you can read a file, and use File:explode("\n").
First line would be File:explode("\n")[1,string]

ah ok it works thanks alot!

there you got your
