Hello all, any suggestions greatly appreciated.
I know how to get bytes from a file, and write them to another file, using something like the below, but what I want to do is some processing on certain bits before writing them back. Any ideas on how to go about this? I am running this script on Win 32, perl 5.6 
open (IN, "< ./someinputfile") || die $!;
open (OUT, "> ./someoutputfile") || die $!;

binmode IN;
binmode OUT;

my $read = 1;
my $result;

while($read > 0){
    $read = read IN,$result,1;

    #do some processing and checking here.
    #convert the bits to bytes

    print OUT $result;
        
}

How do I convert the byte stored in $result to the 0's and 1's that it represents? Well there is a bit more to it than that, but that would be a good place to start. (Haven't done much file processing in the past).

Thanks in advance,
Gerard
