1：變量相加程序

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data
firstval DWORD 20002000h
secondval DWORD 11111111h
thirdval DWORD  22222222h
sum DWORD 0.code
main PROCmov eax,firstvaladd eax,secondvaladd eax,thirdvalmov sum,eaxINVOKE ExitProcess,0
main ENDP
END main

2：.data? 偽指令聲明未初始化程序，當定義大量未初始化數據時，.data?偽指令減少了程序的大小

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data 
smallArray DWORD 10 DUP(10)
.data?
bigArray DWORD 5000 DUP(?) ;20000個字節，未初始化.code 
main PROCINVOKE ExitProcess,0
main ENDP
END main

3：不用.data? 程序會比使用大

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data 
smallArray DWORD 10 DUP(10)
bigArray DWORD 5000 DUP(?)  ;不用.data?,生的編譯程序將會多出20000個字節.code 
main PROCINVOKE ExitProcess,0
main ENDP
END main

4：等號偽指令等號偽指令與宏定義差不多在匯編器預處理時替換的，不占內存，運行時數值不能變，$當前地址計數器符號，返回當前程序語句的偏移量

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data
selfPtr DWORD $  ;$當前地址計數器符號，返回當前程序語句的偏移量
selfPPtr DWORD selfPtr ;與上面一樣;等號偽指令與宏定義差不多在匯編器預處理時替換的，不占內存，運行時數值不能變COUNT = 10  
array  DWORD COUNT DUP(0)  .code
main PROCINVOKE ExitProcess,0
main ENDP
END main

5：使用$計算數組長度

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitProcess:DWORD.data
list BYTE 10,20,30,40
listSize = ($-list)  ;使用$計算數組長度時$前不能有別的數據myString BYTE "This is a long String"BYTE "any number of character"
Ssize = ($-myString)Wlist WORD 10,20,30,40
WlistSize = ($-Wlist)/2  ;除以WORD的長度.code
main PROCINVOKE ExitProcess,0
main ENDP
END main

6：EQU 偽指令使用，也是類似宏

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data
pressKey EQU <"Press any key to continue....",0>
prompt BYTE pressKey   ;pressKey直接把里面的當做文本數據保存到promptmatrix1 EQU 10*10
matrix2 EQU <10*10> M1 WORD matrix1 ;等于M2 WORD 100
M2 WORD matrix2 ;等于M2 WORD 10*10 <>括號內的數據直接復制到M2.code
main PROCINVOKE ExitProcess,0
main ENDP
END main

7：TextEQU文本宏使用，與EQU類似，如果用<>括號都復制替換里面的內容

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data
contiuneMsg TEXTEQU <"Do you wish co continue(Y/N)？">
prompt1 BYTE contiuneMsg;文本宏可以相互構建
rowSize = 5
count TEXTEQU %(rowSize * 2)  ;分配整數表達式
move TEXTEQU <mov>            ;分配文本
setupAL TEXTEQU <move al,count>P1 TEXTEQU <"proc">
P2 TEXTEQU <P1,"edure">
S BYTE P2     ;S 等于“procedure.code
main PROCsetupAL  ;等于 mov al,10INVOKE ExitProcess,0
main ENDP
END main

8：mov偽指令使用

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data
oneByte BYTE 78h
oneWord WORD 1234h
oneDword DWORD 12345678h.code
main PROCmov eax,0mov al,oneBytemov ax,oneWordmov eax,oneDwordmov ax,0INVOKE ExitProcess,0
main ENDP
END main

9：使用mov處理較小有符號數向較大寄存器賦值

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data
signedVal SWORD -16.code
main PROCmov ecx,0FFFFFFFFhmov cx,signedValINVOKE ExitProcess,0
main ENDP
END main

10：MOVSX偽指令，符號位擴展賦值

.386
.model flat,stdcall.stack
ExitProcess PROTO,dwExitCode:DWORD.data
byteVal BYTE 10001111b
.code
main PROCmovsx ax,byteValmov bx,0A69Bhmovsx eax,bxmovsx edx,blmovsx cx,blINVOKE ExitProcess,0
main ENDP
END main

11：MOVZX偽指令，零擴展賦值

.386
.model flat,stdcall.stack 4096
ExitProcess PROTO,dwExitCode:DWORD.data
byteVal BYTE 10001111b
.code
main PROCmovzx ax,byteValmov bx,0A69Bhmovzx eax,bxmovzx edx,blmovzx cx,blINVOKE ExitProcess,0
main ENDP
END main
