Scripting
Languages are an intermediate stage between HTML and programming languages
such as Java, C++ and Visual Basic. HTML is generally used for formatting
and linking text. Programming languages are generally used for giving a
series of complex instructions to computers. Scripting languages fall somewhere
in between, although scripting languages function more like programming
languages than simple html docs. The primary difference between scripting
languages and programming languages is that, the syntax and rules of scripting
languages are less rigid and intricate than those of programming languages.
Scripting engines are the COM (Component Object Model) objects that processes scripts. ASP provides a host environment for scripting engines and distributes scripts within .asp files to these engines for processing. or eaxh scripting language that is used in coordination with ASP scripting, the related scripting engine must be installed on the web server. ASP makes it possible for a web developer to write complete procedures by using a variety of scripting languages without having to worry about whether a browser supports them all. In fact, more than one scripting language can be used in a single .asp file. In addition, the client browser is unnecessarily to support scripting since scripts are executed in server side. VB is the default scripting language used for primary scripting. One should follow the basic guidelines below while setting the primary scripting language for a page.
Do not set the page's primary scripting language in an include file. One of the key features of ASP is the capability of ASP to use several scripting language procedures within a single .asp file. The user should determine which scripting language s/he will use afterwards inside <SCRIPT> tag. The user should take
care on that when using VBScript (Visual Basic Scripting) on the server
with ASP, two features of VBScript are disabled. Since the ASP scripts
are executed on the server, InputBox and MsgBox are not supported.
CreateObject and GetObject functions are also not supported.
The usage of these statements will cause an error.
