What are the steps to write and execute assembly language program?

Creating Source file:- First write the program using a text editor such as DOS Edit (edit), wordpad, notepad and save the file with . asm extension (e.g. hello. asm). Assembly process:- Once the source file is created next step is to assemble it by using ‘tasm’ command as shown below.

How is assembly code written?

A program written in assembly language consists of a series of mnemonic processor instructions and meta-statements (known variously as declarative operations, directives, pseudo-instructions, pseudo-operations and pseudo-ops), comments and data.

What should I learn before assembly?

IMO, you should be familiar with hexadecimal and binary notation of numbers, bitwise logic operations ( and , or , xor .), and the memory model of your target architecture/OS. Some books/tutorials on assembly programming may explain those things, others may assume that you already know them.
