   • Perl programming: continue block

     Top Answer

     Answered May 11, 2011 · 2 votes

     You can use a continue

     block everywhere it makes sense: with while

     , until

     and foreach

     loops, as well as 'basic' blocks -- blocks that aren't part of another statement. Note that you can use the keyword for

     instead of foreach

     for the list iteration construct, and of course you can have a continue

     block in that case.

     As everybody else said, for (;;)

     loops already have a continue

     part -- which one would you want to execute first?

     continue

     blocks also don't work with do { ... } while ...

     because syntactically that's a very different thing (do

     is a builtin function taking a BLOCK as its argument, and the while

     part is a statement modifier). I suppose you could use the double curly construct with them (basic block inside argument block), if you really had to:

     do { { ...; continue if $bad; ...; } continue { ...; # clean up }} while $more;

   • Perl | Socket Programming

     Socket programming in Perl is a way of connecting two nodes on a network to communicate with each other. Basically, it is a one-way Client and Server setup where a Client connects, sends messages to the server and the server shows them using socket connection. One socket (node) listens on a particular port at an IP, while other socket reaches out to the other to form a connection. The server forms the listener socket while the client reaches out to the server. Before going deeper into Server and Client code, it is strongly recommended to go through TCP/IP Model.

     Any computer system that is on a network needs a local port to transfer data over the internet. This data is directed to the designated system with the use of it’s IP Address. Each and every system receives and sends this data over the network by the ports designated for the respective process. For example, port 80 is the default port to receive information sent from the server. This port needs not to be same always, it can be decided by the user as well. Therefore, a socket...

   • Perl | CGI Programming

     In Perl, CGI(Common Gateway Interface) is a protocol for executing scripts via web requests. It is a set of rules and standards that define how the information is exchanged between the web server and custom scripts. Earlier, scripting languages like Perl were used for writing the CGI applications. And, CGI code called by HTTP server was referred to as the CGI script. Later, the growth of the web caused the increase in need of dynamic content through which CGI applications which were written in other languages instead of Perl became more popular and in demand and were referred as scripts only. The specifics of how the script is executed by the server are determined by the server. CGI applications can perform nearly any task. For example, you can access databases, hold telnet sessions, create Web pages on-the-fly and generate graphics, etc. CGI is having a very simple concept, but creating a CGI application requires real programming skills.
