RE: UCP format and checksum

Hi Ali,

The way to calculate checksum is clearly described in UCP spec.
But I see that you still can not understand this description.
Below there is a perl function to calculate checksum that I use in my projects. 
The input parament is UCP string without checksum.
Hope it will help you

Igor

sub _checksum {
    my $chk = 0; map { $chk+=$_; } unpack("C*",shift);
    sprintf("%02X",$chk%256);
}
