Assembly Language Programming (x86)

Project

Write an assembly language program that accumulates and reports the sales for the Albatross Corporation. The Albatross Company has four salespeople who sell five different products. The four salesperson are each identified by a number from 1 to 4. Each products is identified by a number from 1 to 5. Sales are reported by entering the salesperson’s number, the quantity sold, and the product number. For example, to report that salesperson 2 sold 100 units of product 4, you would enter 2 100 4.

Your program must store the sales data in a two-dimensional array (4 rows by 5 columns). Each row represents a salesperson. Each column represents a product. Initialize the array to zeroes and allow your user to enter data. When the user enters a negative number for a salesman number, terminate the input phase of your program and display a report that shows the total sales for each salesperson and the total sales for each product.

Explanation / Answer

.data ; data section

askfile BYTE "Enter the data file name: ",0 ; here to enter the data file name

fileMessage BYTE "Error while opening file: ",0dh,0ah,0 ; here file message byte used for showing error

fileName BYTE 256 DUP(0)   

byteCount DWORD ?

handle DWORD ?

.code ; main program code here

main PROC

mov edx,OFFSET askfile ; OFFSET askfile to edx

call WriteString ; call WriteString procedure

mov edx,OFFSET filename

mov ecx,SIZEOF filename

call ReadString ; call ReadString procedure

mov byteCount,eax ; move eax to byteCount

mov edx,OFFSET filename ; OFFSET askfile to edx

call OpenInputFile ; call OpenInputFile procedure

cmp eax,INVALID_HANDLE_VALUE ; this code used to compare eax,INVALID_HANDLE_VALUE

je file_error

mov handle,eax ; move eax to handle

jmp Alpha ; here the jump instruction is used

file_error:

mov edx,OFFSET fileMessage ; OFFSET fileMessage to edx

call WriteString ; call WriteString procedure

jmp Omega ; jump omega used here

Alpha:

.data ; .data to reserving the storage of data

BUFFER_SIZE = 17 ; buffer size is 17

buffer BYTE BUFFER_SIZE DUP(?)

bytesRead DWORD ?

.code

; next step is read from file

mov eax,handle ;move handle to eax

mov edx,OFFSET buffer ;OFFSET buffer to edx

mov ecx,BUFFER_SIZE ; move BUFFER_SIZE to ecx

call ReadFromFile ; call ReadFromFile procedure

jc read_error ; jump if carry set used here

cmp eax,BUFFER_SIZE ; then compare eax,BUFFER_SIZE

jl Omega ; after comparing eax,BUFFER_SIZE jl is used

read_error: ; read error

mov edx,OFFSET readMessage ; OFFSET readMessage to edx

call WriteString ; call WriteString procedure

jmp Omega ; jump instruction used here

main ENDP ; END procedure

END main ; END
