Re: [SPARK] Code safety and information hiding ... I'll accept a small number of well documented global variables sometimes if the alternative is worse. ... Each subroutine has some local variables and each package has some state and together they all cooperate according to what the whole is supposed to do. ... Then I decide to break the system into separate processes, and for the sake of discussion what was a subroutine originally becomes a separate process, all communicating using some form of IPC and still cooperating to achieve the supposed goals. ...

Re: Help Constructing Fictional Cross-Religious Movement ... copies of local storage and allows access to the different copies by named reference as an obligatory feature of the language."... I would note, though, that the use of "subroutine" in this explanation seems rather centric to your programming idiom -- I suspect that very few readers, on seeing that, would think that the author was explicitly thinking of subroutines with multiple entry points for doing different things, or of using the subroutine's persistent local data for storing this sort of thing. ... If you, like the Java programmer, didn't have a word for such things, and thought of subroutines as normally being single entry point with no persistent local storage -- would it have been nearly so obvious how to emulate a single-instance object in COBOL? ...
