What Does EQU Mean In Assembly?

What does EQU do in assembly?

PIC Program Development In assembly code, the assembler directive EQU is used to assign a label to a number, which can be a literal, a file register number or an individual register bit..

How are variables defined in assembly?

A variable declaration starts with a label definition (the name of the variable), followed by a . word directive, followed by the initial value for the variable. The assembler supports a fairly flexible syntax for specifying the initial value. For now, we will use simple integer values to initialize our variables.

What is 00h in assembly language?

Consider a very simple instruction mov AL, 00H, it is to move a value 00 (HEX) to the AL register of 8086. When the program is being executed, then the value B400 is read from memory, decoded and carried out the task. Usually, the term statement is used to describe a line in an assembly language program.

What are assembler directives in microprocessor?

An assembler directive is a statement to give direction to the assembler to perform task of the assembly process. … An assembler supports directives to define data, to organise segments to control procedure, to define macros. It consists of two types of statements: instructions and directives.

What is out in assembly language?

Description. Transfers a byte, word, or long from the memory address pointed to by the content of the AL, AX, or EAX register to the immediate 8-, 16-, or 32-bit port address. … The outs instruction transfers a string from the memory byte or word pointed to by the ES:source index to the port addressed in the DX register.

How do you declare a constant in an assembly?

To declare a string constant you can use the EQU or TEXTEQU directive. Both are declared before the data segment in the global scope. Then you can go on to use your named variable in the rest of the code. The TEXTEQU can be a bit trickier.

What are equ?

What is a word in assembly language?

A word is a fixed-sized piece of data handled as a unit by the instruction set or the hardware of the processor. The number of bits in a word (the word size, word width, or word length) is an important characteristic of any specific processor design or computer architecture.
