I don't write new Subroutines, subprocedures are sufficient and 1
construct less is good for readability.
IMHO for beginners using ILE concepts subroutines might still be helpful for
encapsulating and structuring the encapsulated source code.
But as soon as they have learned to think really modular, they'll find out
subroutines are not needed (except may be in a few special situations)
At least it's my experience. When we started with ILE concepts, I thought
without subroutines I'll end up in a clunky, nasty and unreadable code, but
now ... I can't remember when I've written the last subroutine.

Betreff: Re: Are subroutines codependent?
<Nathan>
Be more precise about describing the scope of variables.
</Nathan>
local vars := defined inside a procedure global vars := defined in the so
called global declarations of a module you can widen the scope of vars by
keyword export in global definitions ( I don't use this and I recommend not
to use it!°!!) you could limit the scope to bind by copy by binder language
(I don't use
both)
I don't see any need to change existing programms by replacing subroutines
by subprocedures.
I don't write new Subroutines, subprocedures are sufficient and 1 construct
less is good for readability.
