A compiler is a program, written in an implementation language, accepting text in a source language and producing text in a target language. Language description languages are used to define all of these languages and themselves as well. The source language is an algorithmic language to be used by programmers. The target language is suitable for execution by some particular computer.
If the source and target languages are reasonably simple, and well matched to each other, the compiler can be short and easy to implement (See Section l.A.2 of these notes). The more complex the requirements become, the more elaborate the compiler must be and, the more elaborate the compiler, the higher the payoff in applying the techniques of structured programming.
