On a side note, I think the PDF are definitively the most popular for the tutorial now. Look at the downloads for the tutorials that got HTML, DOC and PDF. HTML might be lower cuz it's not available as an online website, though.

I really like the tutorials Hot Dog!  I've read them so far (1-5) and it's inspired me to give Asm another try.  Yours are really well written and have taught me some stuff that confused me in Asm in 28.  Awesome job!  I can't wait to grab 6 off the printer!

Lesson 5 was one I was really nervous about, ztrumpet.  Thanks for the input!

I did not even know Lesson 5 was even posted at all. Unfortunately, though, I don't think I will be able to read the tutorial again until the next few months, because I cannot really concentrate well enough to tell if there is anything to improve on the tutorial, especially about ASM.

Also suggestion:

It's typical on web forums that when someone posts his updates in a locked topic, but not announcing them in the open discussion, people will forget or not comment. When you post one or two new tutorials, I think you should announce it in this topic too, like Quigibo does with Axe parser downloads

Yeah, you're right about that.

With that in mind, tutorials #6 and #7 are up.

I've posted lesson #8.  An html will be coming later, when I can edit it on my "powerhouse" computer instead of my laptop

For this:
Quote
ld a, 250
ld e, 6
add a, e ; Remember that a cannot be bigger than 255, so it resets to zero
should you say that a is zero b/c 256==0 (mod 256) (or something like that)? because replacing that 250 w/a 253 would make a 3 after the add.
Other than that clarification (maybe) I found that lesson pretty good.
Oh, to answer your question (why ld a,0 doesn't reset the zero flag), IIRC it's because the flags aren't affected by ld (except for ld a,i and ld a,r). You're not performing anything requiring the ALU or doing anything truly requiring the flags in general, so they aren't changed.

Previous lessons explain that going over 255 will reset the number to zero and then continue adding up.  When I talked about 200 + 100, I explained that it would equal 44, so I think the reader will understand that 253 + 6 would be 3.
