Did you mean: Is there a way for a subroutine to
react to a call with to many
arguments?

sub accept_max_5_arguments {
die 'too many arguments!' if @_ > 5;
}

sub accept_max_x_arguments { # apart from the
first
my $maxargs=shift;
die 'too many arguments!' if @_ > $maxargs;
}

If this does not help: Could you, long time
posting
list member, clarify your
question?

Why is it so many people on the list are
sarcastic???
example from Dani: "Could you, long time posting
list member, clarify your
question?"

Sarcasm was not intended - I'm simply not a native
english speaker and I don't
mention it in every post :-)

What I wanted to say - without offending you - was:
You asked a lot of
questions, therefore have a lot of experience with
this list, and should know
that and how the questions influnce the answers. As
more precise the
question, as more precise the answer can be (mostly
not from me ;-) ).
["precise" is hardly the correct english word,
but...]

This does not help the situation.
Anyway, I will claify. Is there an inheriant Perl
rule, one that does not require you to code one
up,
that disallows a subroutine to pass too may
arguments
to another subrountine

I don't know of such a thing. How should such a
feature "don't allow too many
arguments without coding something that specifies
'many'" be implemented?

Christian mentioned prototypes, maybe that's what
you're looking for, but they
should be avoided, they do more than just defined
the maximum of possible
arguments, and involve some sort of "coding".

or scalar?

I never heard of a way to pass arguments to (normal)
scalars in perl. Somebody
else may know more.

Likewise, is there a inheriant Perl rule, one that
does not require you to code one up, that
disallows a
subroutine to store too many arguments in @_?

If not then yes your example will suffice.

I don't think there is such a rule, but wait for
other answers.


Dani


I was not offended, just a little bothered b/c I am
only trying to learn more. Yes, now I see how I
should of been more precise and yes that word fits
well in this context, but all in all my question was
answered and I am reading the perldoc.
