|  Re: Assembly and interrupts: my first attempt. Help needed!
Hi again! I don't want to annoy you, so I try to keep my replys short.
@Rybags: I didn't know CPU goes faster when raster is in the "dead" zones, it is interesting! Thank you for the hint!
@Csabo: First of all, thank you for your help. It is exactly the kind of suggestions I was looking for 
I used for a while Plus4IDE (as you already suggested me in a previous message), but I had some problems. So, I moved to Notepad++, that's an editor with which I feel very comfortable. I can run the compiler using the NPP Exec plugin. Besides that, the included sources in Plus4IDE were very useful to me!
About your "if it's not broken, don't fix it", I agree with you. But, since I'm not an expert 6502 programmer, I was wondering if there was a better way to achieve my same result. Rybags gave me some good suggestions.
At this moment, I have a very speciic question, that is:
"what is the fastest way to obtain the text screen address from X,Y coordinates (with x=[0,39] and Y=[0,24])?"
