I admire the people who managed to learn assembly back in the 20th century when tutors were ridiculously expensive and the internet wasn’t at anyone’s disposal.

[@zeektm1762]

Assembly being made in the 1940s/1950s was not that long of a time before C and its precursors arrived. Assembly is very difficult to manage and write when you have to deal with the needs of modern programs. The C language was used in the late 1960s and most programmers in the 1980s at least from my experience were using higher level languages than assembly for most tasks

[@punkgrl325]

@@zeektm1762 Yep. BASIC got pretty popular by the mid-70s to well throughout the 80s when C++ was born.

[@stavros222]

knowing another programming languages make assembly harder because you are expecting this language to be like every programming language but its even harder assembly is more strict than other languages and its not simple

[@VoidHalo]

There was plenty of documentation for computers, processors and chips back then. Look up the datasheet for the 8086 and you'll see an example of what was, and still is used by people to learn this stuff. Nobody serious about this learns JUST from KZbin videos. They make fine supplements, but ideally you would watch (or attend) lectures on computer science, specifically cpu architecture, read textbooks on the same, and read all the documentation you can get your hands on inside and out. Anything you don't understand, look it up, at least in modern times. Back then, if you didn't understand something, you would ask a professor, a TA, or if you're not in academia, like myself, look up alternative resources and read about the same thing, but explained in a different way. THIS is where KZbin videos are most useful. You can only include so much information in a video, but there's no limit to the amount of information you can include in reference/academic material. And if you really want to learn about it, and understand it as intuitively and intimately as possible, an abundance of information should be a good thing. Although, having ADHD myself, I totally understand how it can be overwhelming. I still have issues with that, but if you just take your time and be persistant, you'll really start surprising yourself at what you can understand and do. In this video, he uses an 8086 emulator called Emu8086 (of all things!). It's a very useful tool for learning 8086 assembly, as well as learning about how 8086 based computers worked. I'm sure you saw a decent amount of what it can do in the video. Unfortunately it's not free, but I believe there is a 30 day trial available. And it doesn't cost much more than $20 or $30, I think. Or it's floating around Bit Torrent, if you're a bit less scrupulous. =P. Whether you're using the emulator, or just following along with the video, the 190 page help file is extremely useful, and packed with information. Though if you're completely new to assembly/programming, it may be difficult to follow. I remember having trouble with it some years ago when I first started. Best of luck to you! www.philadelphia.edu.jo/academics/qhamarsheh/uploads/emu8086.pdf

1. Two numbers C1 and C2 are stored in memory. The operation between these numbers is dictated by the bits 5 and 6 of another number C3. The possible two cases are (a) If bit 5 of C3 =1 and bit 6 =0, then C1 = (C1 AND C2) OR F0 H C2 = (C1 XOR C2) AND F0 H (b) If bit 5 =0 and bit 6 =0, then C1= (C1 AND 07 H) OR C2 C2 = (C2 OR 90 H) XOR 50 H Otherwise-No operation.

Please what's the difference between this tutorial video and the video playlist tutorial of Assembly Language for x86 Provessors" (Sixth Edition) by Kip R. Irvine? Thanks in advance

[@grazingrockproductinformat2687]

In your explanation of je/jne you are saying the difference to jz/jnz is that the equality jumps don't look at status codes, just equality? That's definitely incorrect - there is NO difference between jz and je, as there is no difference between jne and jnz; both pairs translate to the same binary opcode - je and jz are literally the same. Consequently, there is no difference between them. The different mnemonics only serve the purpose to make your human-readable program easier to emphasize the purpose in the respective context. The CPU doesn't care, since it cannot even see a difference between jz and je.

hey can you create a program tutorial on how to create a converter of a decimal to any other base like hexadecimal, binary or octa

[@grazingrockproductinformat2687]

Hexadecimal to binary? you're joking, aren't you? A hex digit is a complete representatio of 4 binary digits - so converting between those 2 should be no effort, should it? For the more generic case of radix x (x=10 or whatever else), I suggest reading up on Horner's method - essentially, continuously dividing by the desired radix, which gives you a remainder (the "digit") and the quotient (which you use to continue to divide)

How do you perform input and operation in more than 1 digit number? For example, 50-20. Or ask the user to enter 2 digit number??

[@Xyklonikus]

Nice one mate. In the hello world would you do lea dx, message instead of mov dx, offset message?

[@meysor6204]

I would, [lea dx, message] is pretty much the same as [mov dx, offset message]. LEA means load effective address which means you are loading or moving or technically "copying" the base+offset (address) of the variable named message going to DX. Invoking service 9+int 21h will instruct the computer to keep printing out the characters in your variable message one at a time until it encounters the "$" which is the marker to stop.

[@joaquimjesus6134]

i have 1 question key: why there are several versions of Assembly? i'm not speaking about CPU or OS... but some use ';' for comments and others use '#'... and some use '$' for use the register names and more differences that i have seen.

[@mihirkohli4804]

because every cpu use to code differently

[@joaquimjesus6134]

@@mihirkohli4804 thanks for correct me

[@grazingrockproductinformat2687]

because there are different manufacturers of assemblers (=translation programs of assembly language to binary). Some differences are small (which character is used for comments, for example), other difference can be sizable - Intel notation for the x86 assembler has exactly the opposite data flow direction of AT&T assembler for the exact same CPU, so both translate to the same binary code. Essentially, the answer is the same as in all cases of "why do they use a different language?" - because they can.

[@joaquimjesus6134]

@@grazingrockproductinformat2687 so for we program Assembler we must see if we use: - Windows or Linux; - if CPU is X86 or 32 or 64 bits(on 64 or 32 can we use the X86 code?); - and if is Intel or AMD.. right?

[@grazingrockproductinformat2687]

@@joaquimjesus6134 All of that is important - but none of that makes the choice of assembler language representation. You can use Intel notation on Linux or on Windows, for x86 or x64. You can also use AT&T notation on Windows or Linux, for x86 or x64. Whether for AMD chips or Intel chips, that is fairly irrelevant - but the capabilities of the specific chip you are running on, THAT makes a huge difference. For example, 64-bit-mode requires a x64 CPU (either Intel or AMD), 32 bit mode requires that your operating system allows you to run in 32-bit mode (especially when it's a x64 CPU). There is a whole bunch of instruction set "extensions" such as SSE, AVX, AVX2, AVX512, BMI and so on - before you use any instruction contained in such instruction set, you must ask the CPU if it supports those extensions (the manuals of AMD as well as Intel have quite a lengthy section about how to do that). But again - none of the is related to the original question of why there are different versions of assembly language representation - for ALL of that stuff, any assembler manufacturer can make up their own way of writing it...
