Can Someone help me on this...

[Warlock]

Look at this

mov ax,09
mov ax,9
mov ax,09h

is there any different?

If yes, what is the different...I am new to assembly...

The third line takes a hexadecimal value : 09h

[jj2007]

The third line takes a hexadecimal value : 09h

Which happens to be identical to the decimal value 9 :wink

[Warlock]

So this mean that the

mov ax,09   
mov ax,9

is both the same.

mov ax,09h is different.(Decimal value 9)

Right ???  :wink

For all three forms the assembled instructions are the same:

0B67:0100 B80900        MOV     AX,0009
0B67:0103 B80900        MOV     AX,0009
0B67:0106 B80900        MOV     AX,0009

The only differences I can see would be in the steps that the assembler goes through to convert the constant operand into a value.
