Re: Passing hash references

Since $names is already a hashref, there is no need to reference the reference again. Please change

my $valid_names = &validateNames(\$names);
[download]

my $valid_names = &validateNames($names);
[download]

in your sub validateNames you can access the hashref with the -> operator.

sub validateNames{ 
  my $valid_names=shift; 
  print $valid_names->{SCM555}->{email};
  print $valid_names->{SCM556}->{name};
}

Boris, Just to be consistant with the original poster's code style, whether that's the way you do it or not (it happens to be the way I do things, but it seems I'm in the minority ;->), the arrow operator after a close-brace is not required: `print $valid_names->{SCM555}{email};` [download] Rhodium - note, too, that the quotes inside the braces are optional. I prefer without the quotes (unless required - which they are for certain things), but I do recommend consistancy, even if you disagree with other aspects of my coding style ;-) `print $valid_names->{'SCM555'}{'email'};` [download]	[reply] [d/l] [select]
