A declaration associates certain characteristics and structures with an identifier. In an ALGOL program, every identifier must be declared before it is used. The compiler ensures that subsequent usage of an identifier in a program is consistent with its declaration.
In this section, the ALGOL declarations are listed and discussed in alphabetical order. In many cases, the entire syntax diagram for a declaration is divided into smaller segments, and each segment is discussed in turn. Each declaration is accompanied by examples of its use.
