Procedures are an alternative to methods. Both have the same functionality, but procedures are not attached to classes or instances. They can, however, be declared inside a class. In that case, the procedure can only be called from code within the class and can reference class properties and class-specific tokens like self and super.
You can make a procedure public (usable by other scripts) by listing it in the public section of a script and giving it an export index.
You can declare temporary variables (local to the procedure) by including a &tmp token after the procedure parameters, and following it with a list of temp variable declarations.
(procedure (<ProcedureName> [<ParamName1> <ParamName2> ... &tmp <TempVar1> <TempVar2> ...]) <code> )
(procedure (SomeProc) (PrintingProc "Hello World" 60 80) ) ; This is a public procedure so any other script can use it (public PrintingProc 0 ) (procedure (PrintingProc String X Y &tmp result) (= result (+ 1 2 3)) (Display String dsCOORD X Y) ) ; An example of using it with a class (class SomeClass (properties top 20 left 0 bottom 100 right 40 ) (method (someMethod) (someProc) ) (procedure (someProc) (= top 50) ; sets SomeClass:top to 50 (= right 100) ; sets SomeClass:right to 100 ) )
