Hey! I'm a beginner in Assembly language. I want to know the difference between a declaration enclosed with ' ' and without it.
For example,
variable1 db '0'
variable2 db 0

I know that the one with '' is when printed, it will show what's inside the ''.

Thanks~ :)

Additional question: When I'm inputting a character, the inputted character is in what format? Is it enclosed with ' ' or not?
This is the code I used for character input.

mov ah, 01h
int 21h
