Now write assembly language, structured like to write high-level languages, very convenient. Do not believe? You look at the following small program written know the matter, there is no jump, the complete structural design. Finally, a small sum with Glow Glove article for all to learn information.
;------------------------------------------------- ------
; Example: a factorial data
; If the result is smaller, can be placed in EAX register
; If the result is smaller, can be placed in EDX: EAX register
; File Name: 7.asm
.386
. Model flat, stdcall
option casemap: none
include windows.inc
include masm32.inc
include kernel32.inc

. Data?
CharOut db 100 dup (?)
. Code
OutEdxEax PROTO: DWORD; to EDX: EAX in the output string data into decimal form!
OutEdxEax proc lpString; example: EDX = 0, EAX = 01234567H, then the converted string is:
->''19088743'', 0
mov edi, lpString; point to store the address of the results
mov esi, lpString
mov ecx, 10; converted into decimal
. While eax! = 0 | | edx! = 0
push eax
mov eax, edx
xor edx, edx
div ecx
mov ebx, eax
pop eax
div ecx
add dl,''0''
mov [edi], dl; store results
inc edi
mov edx, ebx
. Endw
mov BYTE ptr [edi], 0; string to 0 to end
dec edi
. While edi> esi; results before the change, the change after the former!
mov al, [esi]
xchg al, [edi]
mov [esi], al
inc esi
dec edi
. Endw
ret
OutEdxEax endp
start:; program starts
xor eax, eax; store the results of the registers EDX: EAX = 1
xor edx, edx
inc eax
mov ecx, 20; calculate the factorial of 20. Can not be greater than 20, otherwise it will overflow, the result will no longer be correct!
. While ecx> 0
. If edx == 0; results in the EAX
mul ecx
. Else; result in EDX: EAX in
push edx
mul ecx
pop ebx

. If edx == 0; results in the EAX
invoke dw2a, eax, addr CharOut
. Else; result in EDX: EAX in
invoke OutEdxEax, addr CharOut; with our own program transformation!
