User-defined functions and procedures Foundation

User-defined functions and procedures provide the structure for Xbase++ programs. The difference between a function and a procedure is merely the presence of a return value: functions have a return value (sometimes termed the function value) and procedures return no value.

Functions and procedures are declared using the keywords FUNCTIONand PROCEDURE. This defines a section of program code and identifies it using an identifier. This section of code is then executed when the identifier for the function or procedure appears in program code.
