Threads play a major role in applications programming today. For example, most Web servers are threaded, as are many Java GUI programs. Here are the major settings in which using threads has been founded convenient and/or efficient:
• Programs with asynchronous events:
Here the program must be ready for various events, but does not know the order in which they might occur. For example, in Sections 3.1 and 3.2, we have a network server connected to several clients. The server does not know from which client the next message will arrive. So, we have the server create a separate thread for each client, with each thread handling only its client.

So, you’ve never programmed before. As we go through this tutorial I will attempt to teach you how to program. There really is only one way to learn to program. You must read code and write code. I’m going to show you lots of code. You should type in code that I show you to see what happens. Play around with it and make changes. The worst that can happen is that it won’t work. When I type in code it will be formatted like this:
##Python is easy to learn
print “Hello, World!”

Crystal Reports has enjoyed a long association with Microsoft and has shipped with Visual Basic (and subsequently Visual Studio) as the default report writer since 1993. Developers have traditionally had a love-hate relationship with Crystal Reports; they loved the functionality it provided and the free run-time license, but they hated having to upgrade to the latest version to get the features they required. Another complaint was that reports could not be created or modified programmatically; they could be created only through the user interface (UI) with either the developer UI with Visual Studio or the consumer UI with the Crystal Reports retail package.

What Are Scripting Languages?
Languages like C and C++ allow a programmer to write code at a very detailed level which has good execution speed (especially in the case of C). But in most applications, execution speed is not important, and in many cases one would prefer to write at a higher level. For example, for text-manipulation applications, the basic unit in C/C++ is a character, while for languages like Perl and Python the basic units are lines of text and words within lines. One can work with lines and words in C/C++, but one must go to greater effort to accomplish the same thing.

The EPICS toolkit consists of a set of software components with which Application Developers can create a control system. The basic component types are:
•OPI
Operator Interface. A UNIX- or NT-based workstation or PC which can run various EPICS tools—the “clients.”
•IOC
Input Output Controller. A VME/VXI-based chassis containing a Motorola 68K or PPC processor with various VME I/O modules for analog and digital signals, and for access to field buses such as Allen-Bradley, GPIB, CANbus or CAMAC.
•LAN
TCP/IP-based Local Area Network. A communication network which connects the IOCs and OPIs. EPICS provides a software com- ponent, Channel Access, which provides network transparent commu- nication between every client—such as OPI—and an arbitrary number of servers—such as IOC.
