Maybe this is not the place to ask this question, but I will have a test and I do not understand the difference between MOV and MOV ptr.
for example, if we have in language c "unsigned char x, y", in assembler if we want "X = 2" we use
MOV x, 2
but if we have "unsigned tabbyt char"and we want" tabby= 15 "is already used
MOV octet ptr tabby , 15.
Can any one explain me the difference, and when should we use MOV and when should we use MOV ptr?
thank you so much
