Assembly Language Codes

Lists Main

Assembler programs are written with short abbreviations called mnemonics; in other words, instead of writing GOTO, the programmer writes JMP (jump), or even BRA (branch). These instructions are frequently abbreviated into total incomprehensibility. Of course, we all know that abbreviations are arbitrary. Anyone who has spent any time programming in assembler knows that all computers can be programmed using an undocumented set of instructions. Frequently, when an error is made writing a program in assembler, a user can actually see the program executing the undocumented instructions. These instructions vary from machine from machine, but all computers have a certain set of them in common. As a service to humanity, here is a list of these common instructions for the first time.
