In this guide, we will discuss Memory Management in Assembly Programming Language. The sys_brk() system call is provided by the kernel, to allocate memory without the need of moving it later. This…

In this guide, we will discuss File Management in Assembly Programming Language. The system considers any input or output data as stream of bytes. There are three standard file streams…

In this guide, we will discuss Macros in Assembly Programming Language. Writing a macro is another way of ensuring modular programming in assembly language. A macro is a sequence of…

In this guide, we will discuss Recursion in Assembly Programming Language. A recursive procedure is one that calls itself. There are two kind of recursion: direct and indirect. In direct…

In this guide, we will discuss Procedures in Assembly Programming Language. Procedures or subroutines are very important in assembly language, as the assembly language programs tend to be large in…

In this guide, we will discuss Arrays in Assembly Programming Language. We have already discussed that the data definition directives to the assembler are used for allocating storage for variables.…

In this guide, we will discuss SCAS Instruction in Assembly Programming Language. The SCAS instruction is used for searching a particular character or set of characters in a string. The…

In this guide, we will discuss CMPS Instruction in Assembly Programming Language. The CMPS instruction compares two strings. This instruction compares two data items of one byte, word or doubleword,…

In this guide, we will discuss STOS Instruction in Assembly Programming Language. The STOS instruction copies the data item from AL (for bytes - STOSB), AX (for words - STOSW)…

In this guide, we will discuss LODS Instruction in Assembly Programming Language. In cryptography, a Caesar cipher is one of the simplest known encryption techniques. In this method, each letter…
