the code that I do research and modify myself does not work. As I'm a beginner, I don't have the ability to debug my program lead I have no choice but to solve the problem, then I tried to modify my code many times but still not work as well... the code is actually should accept the 4-digit input and 2-digit input from the user and multiply both of them then display the sum. Here is the full code
.MODEL SMALL
.STACK 64
.DATA
msg1 db 13,10, "Enter the price of package (4 digit allow): $"
msg2 db 13,10, "Enter quantity of package (2 digit allow): $"
msg3 db 13,10, "Total: "
amount db 4 dup("$")
qty db 2 dup("$")
result db 7 dup("$")
.CODE
