I in to the program stack space, found that I don't care the data into 30 h, or 20 h, when you use the debug for memory will always be more out of a line, which makes me very fan, because according to the thinking of the book, my program begins offset 0, the first line is the data, the following line is to obtain the stack space, normally line is instructions below again, but without reason of empty out a line, why? It is best to go into more detail about, thank you! I don't have a lot of points, please don't abandon
The following is a code and images:
Assume cs: code
Code segment
Dw 0123 h, 0456 h, 0789 h, 0 abch, 0 defh, 0 fedh, 0 cbah, 0987 h
Dw 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
Start: mov ax, cs
Mov ss, ax
Mov sp, 20 h
Mov bx, 0
Cx, mov 8
S: push cs: [bx]
The add bx, 2
Loop s
Mov bx, 0
Cx, mov 8
S0: pop cs: [bx]
The add bx, 2
Loop s0
Mov ax, 4 c00h
Int 21 h
Code ends
The end start
