## 7.3 Functions (plural)

This chapter gives a complete reference of all functions and commands of the PLURAL kernel, i.e. all built-in commands (for the PLURAL libraries see PLURAL libraries).

The general syntax of a function is

                       [target =] function_name (<arguments>);

Note, that both Control structures and System variables of PLURAL are the same as of SINGULAR (see Control structures, System variables).
