No, I agree with you completely. There's no reason to use a subroutine.
There's no reason why they still need to exist in the language, aside from
backward-compatibility.

If the arguement for still using subroutines is "I need to set global
variables, and it's bad to do that in a subprocedure" then I don't think
you have a logical argument!  The person who makes this argument has been
told by someone that global variables are bad in a subprocedure, but s/he
doesn't understand WHY.

There are distinct advantages to eliminating the use of global variables
and having well-defined interfaces to your routines. The use of global
variables in a subprocedure is discouraged BECAUSE you lose those
advantages.  However, it's IMPOSSIBLE to get those advantages with EXSR.
If you're going to throw the advantages away, then there's absolutely no
value to avoid doing it in a subprocedure.
