Hi Eugene,

This looks like a typo.  The field length should be 4, not 5.  There
once was a Flags field, but as it had no obvious use, so it was
removed.  Obviously that part of the text wasn't updated to reflect the
change - I'll update in my working copy and it will be in any further
releases!

Thanks,

Rick
