[amibroker] Re: JavaScript Problem with Array

["Mike" <sfclimbers@xxxxxxxxx>]

You need to store the value that you have read, then write that value. Unless the lines in the file are very very long, a simple string will do.

var line;
var fso, ts;

var ForReading = 1, ForWriting = 2, ForAppending = 8;
var TristateUseDefault = -2, TristateTrue = -1, TristateFalse = 0;

var before = "C:\\Temp\\before.csv"
var after = "C:\\Temp\\after.csv"

fso = new ActiveXObject("Scripting.FileSystemObject");
ts = fso.OpenTextFile(before, ForReading, false, TristateUseDefault);

line = ts.ReadLine(); // First line
line = ts.ReadLine(); // Second line
ts.Close();

ts = fso.OpenTextFile(after, ForWriting, true, TristateUseDefault);
ts.WriteLine(line);
ts.Close();
