Hello. I'm new here and would like learn Hex for z80 Calculators... ASM in 28 days makes me just like that smily . Can anybody please help?

If you want to learn hex, Xeda is the most knowledgeable about that I think.
First you need to understand all the mechanics behind asm though.

Since hex is a less understandable form of ASM, if you can't get around ASM don't expect anything from hex. Hex is really if you don't have a computer but want to do ASM anyway (like Xeda and I did, but I'm definitely stupid compared to Xeda when it comes to hex (and ASM) programming).

Or... Do as the name suggests. One day, one lesson. Even though I read it much quicker than that and didn't try any of the examples, I had some pretty strong programming knowledge including Axe and some z80 asm. If you're a total n00b, Hot Dog's tutorial should be around here somewhere (TheCoder1998, that quote is for you ).

Also, here's an idea: put the 28 days tutorial aside for a few weeks, and then look at it again.
Eventually you'll get the hang of it

Yep, this is a really good way of doing it. I still learn things every so often when I reread it. I made this chart that is kind of compact, but it has notes about how to use certain types of instructions.

I think the best way to get a handle of how assembly works, you should try to learn integer counting systems like binary, and hexadecimal. It will all make a lot more sense.

Note: Hex is not a different programming language than Z80 assembly. It's just a different way to display stuff. You can display your posts in hex, you can display code in hex, you can display image data in hex. Same for binary or base-64. In ASM's case, hexadecimal is just a different way to display the code (instead of english acronyms and syntax you just display it in hexadecimal form). However, ASM is very different than TI-BASIC if you are used to the latter, so good luck. I don't do ASM myself, but if you ask help in the right forum section on Omnimaga (welcome, by the way! ), people will be happy to help. Also, Hot Dog's tutorial can be handy for visual people to understand certain concepts if used with ASM in 28 days, because it provides more visual examples.

I have learned to program in assembly on the computer first using mostly ASM in 28 days and an assembler, which was probably a lot easier than learning to program directly in hex. When I wanted to program it without carrying my laptop around with me, I learned to program in hex on the calculator, and I used Deep Thought's opcode table as a reference for the opcodes. Calcsys is also an incredibly useful on-calc program for disassembling your program and looking at other people's programs closely. WikiTI is also a good resource.

LOL at the Xeda's native language thing. I think she's the only one to have started with hex actually.
