Array in assembly language programming

Array in Assembly Language Programming

Array can be seen as collection of variables. 

An variable is declared as :

a DB 2

b DB 3

c DB 4

Where an array is declaed as:

d DB 2, 3, 4

There is use of DUP operators :

If array is like this,

a DB 2,2,2,2,2,2,2,2,2

Than using DUP operator,

a DB 9 DUP(2)

And is array is like this,

a DB 1,2,3,1,2,3,1,2,3

Than using DUP operator:

a DB 3 DUP (1,2,3)

The is use of index number in array like other programming languages.

For example,

a DB 1,2,3,4,5,6

ArrayName[Index Number] = Value

a[0] = 1

a[1] = 2

a[2] = 3

a[3] = 4

a[4] = 5

a[5] = 6
