Re: Prototyping - is it necessary?

[Codon]

You have another bug in your code (or you transcribed it incorrectly):

(my $datafile, $chomp) = @_;

my is not going to apply to $chomp. Under strict, this should throw an error Global symbol "$chomp" requires explicit package name.

Try this instead:

my ($datafile, $chomp) = @_;

Yes, I caught that bug after my post. Originally I had a statement before

(my $datafile, $chomp) = @_;

That read,

my $chomp = 0;

... but I removed it knowing that if I could remove the prototyping and only pass in a value for $datafile then $chomp would automatically be set to undef. I forgot to move "my" outside the parentheses. Poof! a bug!
