Thank you for your reply. In fact, I'm a C programmer. And I want to write a network client program for the purpose of simulation. My network protocol is like this: String length(4 bytes, big endian) plus the real string. For simple simulate purpose, I'll limit the string length to less than 256. So I've got one byte containing the length of the string. The other end is written in C++. I‘ve got a solve method with sprintf. But I'd rather use a way more perlish.:) -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
