Find more about the FileSystemObject object at http://msdn.microsoft.com/en-us/library/aa242706(v=vs.60).aspx. For good VBScript, I recommend:

• Option Explicit to help detect typos in variables.
• Function and Sub to improve readilbity and reuse
• Const so that well known constants are given names

Here's some code to read and write text to a text file:

Option Explicit

Const fsoForReading = 1
Const fsoForWriting = 2

Function LoadStringFromFile(filename)
    Dim fso, f
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set f = fso.OpenTextFile(filename, fsoForReading)
    LoadStringFromFile = f.ReadAll
    f.Close
End Function

Sub SaveStringToFile(filename, text)
    Dim fso, f
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set f = fso.OpenTextFile(filename, fsoForWriting)
    f.Write text
    f.Close
End Sub

SaveStringToFile "f.txt", "Hello World" & vbCrLf
MsgBox LoadStringFromFile("f.txt")
