Topics of My Program Adds the sales tax in the Price

list of items and replace the Price list with the Calculated

value

Price 1 : 36$Price 2 : 55 $Tax :12%

1. =42. =6

1. 36+4 =40$

2. 55+6=61$

Let’s go to code ….

DATA SEGMENT

PRICE DB 36,55,27,42,38,41,29,39

LEN DW $-PRICE

TAX DB 12

DATA ENDS

Variable 1) PRICE . [Array]

2) LEN . [ Length of Array ]

3) Tax . [ 12% ] $-PRICE : $-Name of the array

CODE SEGMENT 

    ASSUME DS:DATA CS:CODE START:       MOV AX,DATA       MOV DS,AX       LEA BX,PRICE

     MOV CX,LEN

LOOP1:           MOV AH,0        MOV AL,[BX]             MOV DL,TAX        MUL DL   MOV DL,100        DIV DL                            MOV AH,[BX]        ADD AH,AL               MOV [BX],AH                 INC BX                      LOOP LOOP1               MOV AH,4CH      INT 21H      ENDS END START

Return to the DOS function.

Increment (++) the address value of BX register .

LOOP LOOP1 : End of the Loop.

Replace the old price by new price

New price = old price + TAX

(PRICE * 12)/100

Multiply element of Array by TAX . Where Tax = 12 .i.e Price[] * 12

Move value of BX register to AL register .

[] is Refered as VALUE.

Clear the garbage value of AH

Len = 8

Base Address of variable PRICE is loaded in DX register.

MOV DEX , OFFSET PRICE

DS AX DATA

1. Data segment Register .2. Code segment Register .
