Hello, i'm new to this forum. I have an assignment to do:
to convert an hexadecimal numbers to decimal numbers. I have the program, but i'm trying to understand it.
There's some parts of code i don;t understand and i can't find in the net what does it mean.

Code:
.data 			;data segment

    row1 db 'Insert hexademical number: $'
    row2 db 13,10,'demical number: $'
    
    number db 5, 0, 5 dup (0) ; 4 numbers (like FFFF) + ENTER symbol 13

.code

Could you tell me how to understand
db 5, 0, 5 dup (0) and
db 13,10


I'm totally new in ALP, so i would be very grateful if anyone could help me
