transfer text from compilation, with a view to subsequent expansion.
A '''compiler''' is a computer program which translates source code written in a high-level [[programming language]] into executable machine code.
Most compilers perform the following actions, sometimes in a single pass over the source code, and sometimes in several passes. Program optimisation may take place before and during the 'code generation' stage.
:'''Lexical analysis''': convert source code into sequence of tokens.
:'''Syntactic analysis''': structure tokens into parse tree.
:'''Semantic analysis''': annotate parse tree with semantic actions.
:'''Code generation''': produce the final machine code.
