Hi

I'm confused. Why can't you just leave everything in Perl's internal format?

#-- set up the vars to be like what Win32::TieRegistry returns (a stri
+ng and a number);
my ($dword, $type) = ( '0x00500000', 4);
if ( $type == 4 )
{
 $dword = hex $dword;
}

printf "Dword:\tdec:%d\thex:%x\n", $dword, $dword;
my $mask = 0x00400000;
printf "mask:\tdec:%d\thex:%x\n", $mask, $mask;
my $flags = 0x00100000;
printf "mask:\tdec:%d\thex:%x\n", $flags, $flags;

my $testdw = $dword & $mask;
my $newdw  = $dword | $flags;

printf "TestDW:\tdec:%d\thex:%x\n", $testdw, $testdw;
printf "NewDW:\tdec:%d\thex:%x\n", $newdw, $newdw;

Results

Dword:  dec:5242880     hex:500000
mask:   dec:4194304     hex:400000
mask:   dec:1048576     hex:100000
TestDW: dec:4194304     hex:400000
NewDW:  dec:5242880     hex:500000

I think you still need the first $dword = hex $dword; as the return from Win32::TieRegistry is a string.
