EQU的三种格式
1.name EQU expression
2.name EQU symbol
3.name EQU <text>
1.expression必须是有效的整数表达式 不能有变量的存在
TITLE name EQU expression include irvine32.inc val1 EQU <10*10> .data val2 dword val1 .code main PROC mov eax,val1 call DumpRegs exit main ENDP end main
TITLE name EQU expression include irvine32.inc .data val1 DWORD 10000H val2 DWORD 20000H .code main PROC val3 EQU 10*20 mov eax,val3 call DumpRegs exit main ENDP end main
2.符号symbol必须是已用”= ”或EQU定义的符号名
TITLE name EQU expression include irvine32.inc .code main PROC COUNT1 = 100h ;用"="已定义 val1 EQU COUNT1 mov eax,val1 COUNT2 EQU 200h ;用EQU已定义 COUNT3 EQU COUNT2 mov ebx ,COUNT3 call DumpRegs exit main ENDP end main
3.<>括号内可以填写任意的文本
eg1
TITLE name EQU expression include irvine32.inc val1 EQU <10*10> .data val2 dword val1 .code main PROC mov eax,val1 call DumpRegs exit main ENDP end main
eg2:
TITLE name EQU expression include irvine32.inc val1 EQU <"memeda",0> .data val2 byte val1 .code main PROC mov al,val2 call DumpRegs exit main ENDP end main
注：EQU与“=”差不多相同，但是EQU不能重定义
TEXTOUT的使用：
1:格式将文本赋给符号
2：格式将已定义的文本宏内容赋给符号
3：格式将整数表达式常量赋给符号
eg：
TITLE TEXTOUT eg include Irvine32.inc Welcome TEXTEQU <"Welcome to assembly"> .data val1 BYTE Welcome val2 TEXTEQU %(100h) rowSize=5 .code main PROC count TEXTEQU %(rowSize*2) count1 TEXTEQU val2 move TEXTEQU <mov> setupAL TEXTEQU <move al,count> call DumpRegs exit main ENDP end main
