Declarations and Statements Foundation

This chapter describes the various declarations used to declare identifiers in an Xbase++ program for the compiler. Functions, procedures and variables are specified using identifiers. Declarations for classes, methods and member variables are discussed in the chapter "Object-Oriented Programming".

After declarations the description of statements follows, which control the program flow within procedures and functions.
