[Giusy]

Hi,
I read a txt file so:

tr.Initialize(File.OpenInput(File.DirInternal, "PARAMETRI.txt"))  
        ROWs=16
        For SS = 1 To ROWs
        strlines = tr.ReadLine
        ....
        Next 
        tr.Close

But I do not Know how to write a file

tr.Initialize(File.OpenOutput(File.DirInternal, "PARAMETRI.txt",False)) 
???

Can someone help me?

Dim TextWriter1 As TextWriter
    TextWriter1.Initialize(File.OpenOutput(File.DirRootExternal, "Text.txt", False))
    For i = 1 To 10
        TextWriter1.WriteLine("Line" & i)
    Next
TextWriter1.Close

ROWs=16

if u write the count of lines before its easier to read.
u can also save/load a map (key/value) with File.

Erel is going to yell at you for using TextReader and TextWriter. I predict he'll say that in most cases, you are better off using File.ReadList and File.WriteList or similar methods.

That's true. The only reason to use TextReader / TextWriter is if you want to use an encoding other than UTF8.
