Accessing an object in a sub-routine

[C GIllespie]

Dear All,

I'm not too sure on the exact terminology, so I hope you will bare with me


In my small script, I have:

my $varA = $f->fault;

How do I pass $f to a subountine, i.e.

sub sub1(
$_->fault; #This is wrong!
)
sub1($f);

Declaring $f as global variable is one way, but are there any others?

Thanks

Colin

$_->fault; #This is wrong!

Sub args come in in @_. Read perldoc perlsub.

sub sub1 {
$_[0]->fault;
}

)
sub1($f);
