@NYYRIKKI: You now the topic says "Basic course for newbies", right 
But I do agree: Using BDOS is better, way better... (I assume you're using BDOS calls, don't feel the urge to disassemble that piece of ML)
BDW: VPOKE is also nice to play with i found out today

Yes, that is correct and I do agree that this is not good example for newbies. How ever this is one of those things that simply can't be done in newbie friendly way... So I thought that it is better alternative to give "unreadable code" that people can adapt to their needs rather than teaching how to do things in a way that causes trouble & compatibility issues later anyway. In this example I used two BDOS FCB functions: #11 Search first entry and #12 Search next entry but I will not explain it better on this topic.
Now please start asking more easy questions 
File handling & BASIC is not the best topic to start learning.
I'll let our Finish friend write part 2.
To bad. Because, I'm a beginner, and this thread is fun to learn so far. (Even i do not understand anything but it makes me curious what you can do in MSX basic and behind that..) At this moment i can only do thing is C# and VB.NET, but that don't help me on the MSX. For now i learned that file handling is a bit complex on the MSX. Not as simple as filehandling in VB
