Read data from an ascii file

I am a beginner with root under win2k, so bear with me. I used it with Linux, though.
I want to perform a rather simple task: read in data from an ascii file and plot it. The problem is I can open the file, but its contents are not read. Even if I copy a macro from the tutorials, which does excactly this, it fails. The worst part is that the tutorials work.
Any idea ?

It is impossible to even try to diagnose your problem from the information that you provide. How do you know that the file is being opened correctly? What do you mean by the contents are not read? How are you trying to read the file? A short example along with what errors you encounter would help. Please read root.cern.ch/root/roottalk/RoottalkRules.html
