Another type of programming language, scripting, are programming languages that manage applications (programs designed to perform specific tasks). Unlike procedural language, scripts can run applications directly from what is called a source code, a form of human-readable instructions that consist of a program. The most popular scripting language available today is most probably JScript; JScript is mainly used for web page development and is structured like this:
<HTML>
<HEAD>
<TITLE>TEXT</TITLE>
</HEAD>
<BODY>
<SCRIPT LANGUAGE="JAVASCRIPT">
<!-- Hiding the code
document.write("TEXT!");
// done hiding -->
</SCRIPT>
</BODY>
</HTML>
JScript is used as a Windows Script engine. By this, it means that Jscript can be used with any application that hosts Windows script engine, an example being the internet and active server Pages. As well as this it means that any application with Windows Script can use several different languages.
JScript was first used in internet explorer browser which was designed in 1996. Jscript with all other active Scripting engines is available through internet explorer, windows script host, and other active service pages.
Another language also designed to write web pages and enhance website development is a mark-up language.
Most commonly known to some as a HTML (Hyper Text Mark-up Language), as this is a very widely spread form of a mark-up language.
This type of language is an array of codes and/or tags that tells the person designing the program what the contents are and the structure and/or what it should display in its final format.
HTML was designed and created in 1991 and holds similarity to that of Jscript as they are both similarly scripted. They both use certain text to display the required format when designing a program.
<html>
<head>
Hello!
</head>
<frameset>
<frame></frame>
<noframes></noframes>
</frameset>
</html>
Object Orientated languages (OOP, object orientated program) are used for the construction of programs, simply by using individual objects to allow flexibility in the development of the program in previous years; in a recent development over the past 15 years it is now common to find object orientated languages within most recent programming languages, this was not always the case as OOP was not commonly used in commercialized software until the 1990s.
A form of an OOP is java, similar to what we have previously covered in scripting languages. As you can tell java and Jscript are created by the same company, Sun Microsystems and created in 1995, Java was the first to be designed.
Now moving on to visual languages; a visual language will allow users to specify programs by manipulating the program features graphically compared to textually. It displays visual expressions and graphic symbols.
The majority of VPLs are based on "boxes and arrows," basically, a number of boxes or circles that are treated as screen objects, connected by arrows or lines.
CODE is a type of VPL allowing users to create sequential programs into parallel ones.
