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.
