Now what should I look out for in those pdf can you hint me

Answer is simple: everything. ;-)


also Mr.Michael Karas I went through the code you sent me , I am still a beginner that amount of code was too difficult to understand I got lost , I tried reading it couple of times.


Study the tutorials and bible first, write lots of simple programs.

If you try and understand a program, don't expect this to happen within a few hours. It can take days to completely understand an existing program. I know that it will take me days to get into all the details of some of the programs written by the more experienced forum members.
If you say you tried reading it a couple of times, you will not get any closer to understanding it. It is not a book one reads. A program must be studied, not read. And by studying I mean following each statement, figure out what it does, and why it does it. If need be write down the states and contents of registers on paper and see what happens.



good luck
