A.2 Lexical Conventions
A program consists of one or more translation units stored in files. It is translated in several phases, which are described in Par.A.12. The first phases do low-level lexical transformations, carry out directives introduced by the lines beginning with the # character, and perform macro definition and expansion. When the preprocessing of Par.A.12 is complete, the program has been reduced to a sequence of tokens.
