Bill, Actually RStyle does not distinguish and always adds a RETURN if missing and will allow syntax RETURN retunvalue
RStyle has no means to determine whether the item is a COMMAND FILE, STORED PROCEDURE, STORED FUNCTION, or TRIGGER. To do so would probably require some form of meta data to indicate intended use.

In the help files, read "using stored procedures." For example, you can call a stored procedure to set a variable to the value after the last "RETURN value" statement. Dennis, you were still the developer of R:Style back in 6.5 when "RETURN value" became a valid syntax. I can't remember what change you had to make to R:Style then, but you had to do something to distinguish it from the RETURN at the end of a command file.
