The FUNCTION keyword starts a function block.

Syntax

FUNCTION <name> AS <type> ([<arg> AS <type>[, <arg> AS <type>]...]) [OVERLOAD] [PRIVATE|SHARED] [STATIC]
  <statements>
END FUNCTION

<name> must be a valid identifer
<type> must be provided and it must be a defined type (internal or user-defined)
The argument list is optional, but the parenthesis () must be included
The OVERLOAD keyword must be given if the function overloads another function with the same name
If the function is defined in a TYPE block, the PRIVATE keyword indicates that the function may only be called from within that TYPE block.
The SHARED keyword indicates that the function is visible from within other code modules
The STATIC keyword indicates that no stack frame is allocated on each function call. See static_vs_dynamic
