Need Help??

Thanks to all for the answers. I understand what happened now. :)

I will ask you this, since you slightly changed the method used to read the data (not that I need to know for this particular case, but just want to increase my understanding in general) - how do I specify reading 16 characters (perhaps UTF-8, for example) versus reading 16 bytes (as in pure binary data?

Thank you again

The behaviour depends on the filehandle. It's documented at the end of read > depending on the status of the filehandle, either (8-bit) bytes or characters are read. Similarly, sysread: > Note that if the filehandle has been marked as ":utf8", Unicode characters are read instead of bytes So, to read UTF-8, open the file handle with the `:encoding(UTF-8)` layer. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

I don't do UTF. Maybe someone else will answer this.	[reply]
