Hi, I have doubt about result of *length(pack('L!',0)) is 4 and not 8* as I assumed on my Windows 8 running on 64-bit cpu. I tested the same pack template on http://www.tutorialspoint.com/execute_perl_online.php and result is 8 there as I assume. I have new instalation of Perl distro strawberry-perl-5.24.0.1-64bit.msi Summary of my perl5 (revision 5 version 24 subversion 0) configuration: Platform: osname=MSWin32, osvers=6.3, archname=MSWin32-x64-multi-thread uname='Win32 strawberry-perl 5.24.0.1 #1 Tue May 10 21:30:49 2016 x64' ... Sincerely Mira

It is correct behaviour as "unsigned long" is 4 bytes on 64bit MS Windows and "L" means exactly "An unsigned long value" see http://perldoc.perl.org/functions/pack.html Using "L" with pack/unpack is platform dependent, consider using some of the platform independent options: q A signed quad (64-bit) value. Q An unsigned quad (64-bit) value. n An unsigned short (16-bit) in "network" (big-endian) order. N An unsigned long (32-bit) in "network" (big-endian) order. v An unsigned short (16-bit) in "VAX" (little-endian) order. V An unsigned long (32-bit) in "VAX" (little-endian) order. -- kmx
