About User-Defined Functions

LSL allows user-defined functions. The syntax is very simple:

<lsl>

return_type variable_name(par1type par1name, par2type par2name,...)

 {
   function_statements;
   .
   .
   .
   return value_of_return_type;
 }

</lsl>

There are no "function" or "def" keywords or function type/inheritance specifiers needed. I have not yet discovered what limits (if any) exist on the length or composition of the parameter list. Multiple types can be used, as shown in the example below. A list can be returned, so a single function can return a list with several values in it. User-defined functions will help keep scripts compact and readable, and allow rudimentary code reuse. The LSL_Style_Guide suggests that user-defined functions should be placed before the default state definition and after user-defined variables. Placing user-defined functions after the first state will result in a Syntax Error.
