The instruction statements are the working part of the language, and they are divided into the following three groups:A machine instruction is the symbolic representation of a machine language instruction of instruction sets, such as:IBM® Enterprise Systems Architecture/390 (ESA/390)IBM z/Architecture®It is called a machine instruction because the assembler translates it into the machine language code that the computer can execute.An assembler instruction is a request to the assembler to do certain operations during the assembly of a source module; for example, defining data constants, reserving storage areas, and defining the end of the source module.A macro instruction or macro is a request to the assembler program to process a predefined sequence of instructions called a macro definition. From this definition, the assembler generates machine and assembler instructions, which it then processes as if they were part of the original input in the source module.The assembler produces a program listing containing information that was generated during the various phases of the assembly process.2 It is really a compiler for Assembler language programs.The assembler also produces information for other processors, such as a binder (or linker, for earlier releases of the operating system). Before the computer can execute your program, the object code (called an object deck or simply OBJ) has to be run through another process to resolve the addresses where instructions and data will be located. This process is called linkage-editing (or link-editing, for short) and is performed by the binder.The binder or linkage editor uses information in the object decks to combine them into load modules. At program fetch time, the load module produced by the binder is loaded into virtual storage. After the program is loaded, it can be run.
