What Is The Equ Directive?

1.	What Is The Equ Directive?
Answer» The EQU DIRECTIVE is used for DEFINING CONSTANTS. The syntax of the EQU directive is as follows − CONSTANT_NAME EQU expression For example: TOTAL_STUDENTS equ 50 You can then use this CONSTANT value in your code, like − mov ecx, TOTAL_STUDENTS cmp eax, TOTAL_STUDENTS The operand of an EQU statement can be an expression − LENGTH equ 20 WIDTH equ 10 AREA equ length * width Above code segment would define AREA as 200.

The EQU DIRECTIVE is used for DEFINING CONSTANTS. The syntax of the EQU directive is as follows −

CONSTANT_NAME EQU expression

For example: TOTAL_STUDENTS equ 50

You can then use this CONSTANT value in your code, like −

mov ecx, TOTAL_STUDENTS
cmp eax, TOTAL_STUDENTS

The operand of an EQU statement can be an expression −

LENGTH equ 20
WIDTH equ 10
AREA equ length * width

Above code segment would define AREA as 200.
