Chapter 14
Using functions and procedures

Free Pascal supports the use of functions and procedures. It supports

• Function overloading, i.e. functions with the same name but different parameter lists.
• Const parameters.
• Open arrays (i.e. arrays without bounds).
• Variable number of arguments as in C.
• Return-like construct as in C, through the Exit keyword.

Remark: In many of the subsequent paragraphs the words procedure and function will be used interchangeably. The statements made are valid for both, except when indicated otherwise.
