'routine_id' is platform independent but in my experience is really only
necessary in situations where your library needs to call a routine provided
by a user of the library (a situation where your library does not know what
the function is).  This is why it's frequently used in Win32lib.  Win32lib
calls event functions that are provided by the user (onOpen, onPaint,
onMouse, onClick, etc.).  If your library does not need to use routines
created by the user (routines defined later in the program) then you should
not need to use it.  Simply define the functions that the user can access
as 'global'.  Routines that are intended to be used only by the libary
(e.g. helper routines that might be used by more than one global routine)
should *not* be declared 'global'.

Hope this clears things up if you weren't too sure about it.  Check the
reference manual on 'routine_id' for other possible uses (which includes a
link to a comprehensive discussion of 'scope' in section 2.4.2).

Good luck,
Brian
