in reply to Printing an Hash

This should keep all of your indentation, though Im not aware of how you want it printed out, so I just put each key and value on a newline

use v5.14; my %hash = (' key' => 'value ',"\tkey2" => "value2\t"); open(FILE,'>>','filename') or die "$!"; while ( my($key, $value ) = each(%hash)){ print "$key\n$value\n"; print FILE "$key\n$value\n"; } close FILE;

[GotToBTru]: that page, strangely enough, never mentions that construct
[LanX]: ; is for optional prototypes
[LanX]: & is codeblock @ array
[GotToBTru]: okay, that is there in the text, not in literal use in any of the examples
[GotToBTru]: the text suggest it is redundant before @
[LanX]: propably ... I also notice new stuff
