Procedures
Keywords that work with procedures.
Description:
These keywords control the declaration and definition of both module-level procedures and member procedures, how they are called, how arguments are passed and how their names are seen externally to other modules. Procedures can also be declared to be executed automatically before any module-level code is executed.
Declaration
Keywords that declare and define procedures.
Linkage
Keywords that specify how procedure names are seen by external modules.
Calling conventions
Keywords that specify how arguments are used when calling procedures.
Parameter passing conventions
Keywords that specify how arguments are passed to procedures.
Variadic Procedures
Macros that allow for an arbitrary number of arguments to be passed to a procedure.
Automatic execution
Keywords that specify automatic execution of procedures.
Miscellaneous
Miscellaneous keywords.
