Because the data includes numbers encoded in 3, 5, 6, and 7 bytes as well.	[reply]

`unpack` doesn't support those sizes directly. You could extract them in parts, then assemble them. `# 3-bytes, network order my ($o1, $o2, $o3) = unpack('CCC', $_); my $n = ($o1 << 16) \| ($o2 << 8) \| $o3; -or- my ($n1, $n2) = unpack('Cn', $_); my $n = ($n1 << 16) \| $n2;` [download] Alternatively, you could add padding. `# 3-bytes, network order my $n = unpack('N', "\x00".$_);` [download]	[reply] [d/l] [select]
