A series of operation codes or instructions available for a particular computer and used to help application programmer to write programs efficiently 某特定计算机的操作码或指令的集合，用来帮助程序员有效地编写程序。
A set of processor - readable opcodes and data . the output of compilers , assemblers , linkers , and locators are files containing object code 处理器能读的操作码和数据。编译器、汇编器、连接器和定位器的输出文件都含有目标代码。
Some variations of this instruction format use portions of the target and source operand specifiers as immediate fields or as extended opcodes 这一指令格式的一些变种使用部分目的和源寄存器操作数说明符作为立即字段或作为扩展的操作码。

In contrast , concatenating a string is pretty much just a case of running a single opcode to append a string variable to an existing string variable 相反，连接字符串操作非常简单，只是运行一个操作码，将一个字符串变量附加到一个现有的字符串变量中即可。
The instruction format indicates that there can be as many as 2 [ 4 ] = 16 different opcodes , and up to 2 [ 12 ] = 4 , 096 ( 4k ) words of memory can be directly addressed 这样的指令格式说明有16 ( 2的4次方)种不同的操作码和4096 ( 2的12次方)字大小的内存存储空间能被直接寻址。
The remaining 26 bits contain fields for operand specifiers , immediate operands , and extended opcodes , and these may be reserved bits or fields 其余26位包含的字段分别是操作数说明、立即（ immediate ）操作数以及扩展的操作码（ opcode ） ，而且这些还可能是保留的位或字段。
To prepare a machine - language program from a symbolic language program by substituting absolute operation codes for symbolic operation codes and in absolute or relocatable addresses for symbolic addresses 从符号语言程序产生一个机器语言程序,就是用绝对操作码代换符号操作码,用绝对地址或浮动地址代换符号地址。

A reference to the opcode string used in marshaling the fields of the structure described by the referenced type description , or returns a null reference nothing in visual basic if there is no information to return 对操作码字符串的引用，该字符串用于封送处理由引用类型说明描述的结构的字段；如果没有要返回的信息，则返回空引用（在visual basic中为nothing ） 。
