汇编常见错误解决⽅法总结汇编常见错误总结Block nesting error嵌套出错.嵌套的过程,段,结构,宏指令或重复块等⾮正常结束.例如在嵌套语句中有外层的结束语句,⽽⽆内层的结束语局1Extra characters on line⼀语句⾏有多余字符,可能是语句中给出的参数太多2Internal error-Register already defined这是⼀个内部错误.如出现该错误,请记下发⽣错误的条件,并使⽤Product Assistance Request 表与Microsoft公司联系3Unkown type specifer未知的类型说明符.例如类型字符拼错,把BYTE写成BIT,NEAR写成NAER等4Redefinition of symbol符号重定义.同⼀标识符在两个位置上定义.在汇编第⼀遍扫描时,在这个标识符的第⼆个定义位置上给出这个错误5Symbol is multidefined符号多重定义.同⼀标识符在两个位置上定义.在汇编第⼆遍扫描时,每当遇到这个标识符都给出这个错误6Phase error between passes两次扫描间的遍错.⼀个标号在⼆次扫描时得到不同的地址值,就会给出这种错误.若在启动MASM时使⽤/D 任选项,产⽣第⼀遍扫描的列表⽂件,它可帮助你查找这种错误7Already had ELSE clause已有ELSE语句.在⼀个条件块⾥使⽤多于⼀个的ELSE语句8Must be in conditional block没有在条件块⾥.通常是有ENDIF或ELSE语句,⽽⽆IF 语句9Symbol not defined符号未定义,在程序中引⽤了未定义的标识符10Syntax error语法错误.不是汇编程序所能识别的⼀个语句11Type illegal in context指定⾮法类型.例如对⼀个过程指定BYTE类型,⽽不是NEAR或FAR12Group name must be unique组名应是唯⼀的.作为组名的符号作为其他符号使⽤13Must be declared during pass 1必须在第⼀遍扫描期间定义.在第⼀遍扫描期间,如⼀个符号在未定义前就引⽤,就会出现这种错误.14Illegal public declaration⼀个标识符被⾮法的指定为PUBLIC类型15Symbol already defferent kind重新定义⼀个符号为不同种类符号.例如⼀个段名重新被当作变量名定义使⽤16Reserved word used as symbol把汇编语⾔规定的保留字作标识符使⽤17Forward reference illegal⾮法的向前引⽤.在第⼀遍扫描期间,引⽤⼀个未定义符号.18Operand must be register操作数位置上应是寄存器,但出现了标识符19Wrong type of register使⽤寄存器出错20Operand must be segment or group应该给出⼀个段名或组名.例如ASSUME语句中应为某段寄存器和指定⼀个段名或组名,⽽不应是别的标号或变量名等21Symbol has no segment不知道标识符的段属性22Operand must be type specifierSymbol alread defined locally以被指定为内部的标识符,企图在EXTRN语句中⼜定义外部标识24Segment paraneters are changed段参数被改变.如同⼀标识符定义在不同段内25Improper align/combin type段定义时的定位类型/组合类型使⽤出错26Reference to multidefined symbol指令引⽤了多重定义的标识符27Operand expected需要⼀个操作数,只有操作符28Operator expected需要⼀个操作符,但只有操作数29Divdsion by 0 or overflow除以0或溢出30Negative shift count运算符SHL或SHR的移位表达式值为负数31Operand type must match操作数类型不匹配.双操作数指令的两个操作数长度不⼀致,⼀个是字节,⼀个是字32Illegal use of external外部符号使⽤出错33Must be record field name应为记录字段名.在记录字段名位置上出现另外的符号34Must be record name or field name应为记录名或记录字段名.在记录名或记录字段名位置上出现另外的符号35Operand must be sizeMust be variable,label,or constant应该是变量名,标号,或常数的位置上出现了其他信息37Must be stucture field name应该为结构字段名.在结构字段名位置上出现了另外的符号38Lefe operand must segment操作数的左边应该是段的信息.如设DA1,DA2均是变量名,下列语句就是错误的:"MOV AX,DA1:DA2".DA1位置上应使⽤某段寄存器名39One operand must constant操作数必须是常数.40Operand must be in same segment or one constant"—"运算符⽤错.例如"MOV AL,—VAR",其中VAR是变量名,应有⼀常数参加运算.⼜如两个不同段的变量名相减出错41Normal type operand expected要求给出⼀个正常的操作数.42Constant expected要求给出⼀个常数.43Operand must have segment运算符SEG⽤错.44Must be associated with data在必须与数据段有关的位置上出现了代码段有关的项45Must be associated with code在必须与代码段有关的位置上出现了数据段有关的项46Multiple base registers同时使⽤了多个基址寄存器.如"MOV AX ,[SI][BP]"47Multiple index registers同时使⽤了多个变址寄存器.如"MOV AX ,[SI][DI]"指令仅要求使⽤基址寄存器或变址寄存器,⽽不能使⽤其他寄存器.49Illegal use of register⾮法使⽤寄存器出错50Value is out of range数值太⼤,超过允许值.例如:"MOV AL ,100H"51Operand not in current CS ASSUME segment操作数不在当前代码段内.通常指转移指令的⽬标地址不在当前CS段内52Improper operand type操作数类型使⽤不当.例如:"MOV VAR1,VAR2".两个操作数均为存储器操作数,不能汇编出⽬标代码53Jump out of range by %ld byte条件转移指令跳转范围超过-128~ 127个字节.出错⼚,信息同时给出超过的字节数54Index displacement must be constant变址寻址的位移量必须是常数55Illegal register value⾮法的寄存器值.⽬标代码中表达寄存器的值超过756Immediate mode illegal不允许使⽤⽴即数寻址.例如"MOV DS,CODE"其中CODE是段名,不能把段名作为⽴即数传送给段寄存器DS 57Illegal size for operand使⽤操作数⼤⼩(字节数)出错.例如:使⽤双字的存储器操作数58Byte register illegal要求⽤字寄存器的指令使⽤了字节寄存器.如PUSH,POP指令的操作数寄存器必须是字寄存器59Illegal uer of CS register指令中错误使⽤了段寄存器CS.如:"MOV CS,AX"CS不能做⽬的操作数60Must be accumulator register要求⽤AX或AL的位置上使⽤可其他寄存器.如IN,OUT指令必须使⽤累加器AX或AL不允许使⽤段寄存器的位置上使⽤了段寄存器.如"SHL DS,1"62Missing or unreachable CS试图跳转去执⾏⼀个CS达不到的标号.通常是指缺少ASSUME语句中CS与代码段相关联63Operand combination illegal双操作数指令中两个操作数组合出错64Near JMP/CALL to different CS试图⽤NEAR属性的转移指令跳转到不在当前段的⼀个地址65Label cannot have segment override段前缀使⽤出错66Must have instuction agter prefix在重复前缀REP,REPE,REPNE后⾯必须有指令67Cannot override ES for destination串操作指令中⽬的操作数不能⽤其他段寄存器替代ES68Cannot address with srgment register指令中寻找⼀个操作数,但ASSUME语句中未指明哪个段寄存器与该操作数所在段有关联69Must be in segment block指令语句没有在段内70Cannot use EVEN or ALIGN with byte alignment在段定义伪指令的定位类型中选⽤BYTE,这时不能使⽤EVEN或ALIGN伪指令71Forward needs override or FAR转移指令的⽬标没有在源程序中说明为FAR属性,可⽤PTR指定72Illegal value for DUP count操作符DUP前的重复次数是⾮法的或未定义73Symbol id already external在模块内试图定义的符号,它已在外部符号伪指令中说明DUP nesting too deep操作数DUP的嵌套太深75Illegak use of undefinde operand( )不定操作符" "使⽤不当.例如"DB 10H DUP( 2)"76Too many valer for struc or record initialization在定义结构变量或记录变量时,初始值太多77Angle brackets requored around initialized list定义结构体变量时,初始值未⽤尖括号()括起来78Directive illegal structure在结构体定义中的伪指令使⽤不当.结构定义中的伪指令语句仅⼆种:分号(;)开始的注释语句和⽤DB,DW等数据定义伪指令语句79Override with DUP illegal在结构变量初始值表中使⽤DUP操作符出错80Field cannot be overridden在定义结构变量语句中试图对⼀个不允许修改的字段设置初值81Override id of wrong type在定义结构变量语句中设置初值时类型出错82Circular chain of EQU aliases⽤等值语句定义的符号名,最后⼜返回指向它⾃⼰.如:A EQU BB EQU A83Cannot emulate cooprocessor opcode 仿真器不能⽀持的8087协处理器操作码84End of file,not END directive 源程序⽂件⽆END⽂件85Data
