Hi monks.

I'm new using unpack function to get data from an external binary source. I'm having trouble getting the right values.

My first value is coded as an unsigned 16-bit integer, little-endian. When I open it with my hex editor, I can see that the two first bytes are coded "DC 20", which represents 8412, which is the value I expect.

My perl code is the following:

my $fh = FileHandle->new;
open ($fh, '<', $filename) or die 'missing file';
binmode $fh, ':raw';
my @values = unpack 'S<', $fh;
print @values;

and provides the value 26950. I really can't figure out where this data comes from. Same if I provide '<:raw' to the open function.

I'm running on Windows 7 64-bit, Perl 5.12.3.

Any idea/suggestion? I'm clueless right now.
