Components Of a VBScript
Script just don't run automatically, there are lots of component that make it work perfectly. VBScript too have structure, VBscript component are as follows
1 - Variables
2 - Functions
Built-in (Intrinsic) Functions
Custom Functions
3 - Subroutines
Built-in (Intrinsic) Subroutines (Also called Statements)
Custom Subroutine (Statements)
4 - Comments and Documentation
Variables :
Variables act as storage areas for different types of data. Variable names must always follow a few basic rules
- Variables are not case-sensitive
- Variables must begin with a letter or and underscore (_) character.
- Variables may contain letters, numbers, and underscores.
Functions :
Functions are a way of performing a task and getting something back. Functions are used to perform special calculations, convert data types, retrieve information, look up information and much more. For example, VBScript has a function named Time( ), which simply returns the current system clock time. There are two types of functions, Built-in (Intrinsic) Functions and Custom Functions.
Built-in (Intrinsic) Functions
Intrinsic functions as mentioned previously are functions that are built into VBScript. Intrinsic functions include string operations, conversions, math functions, time and date functions, and Boolean functions.
Custom Functions
Custom functions are the functions that are build by yourself. You can build your own custom functions and you could probably use it in any number of different scripts.
Subroutines
Built-in (intrinsic) Subroutine (Statement)
A statement is an intrinsic command that accepts zero or more parameters and returns no value. One of the simplest VBScript statements is Beep, which simply makes the computer beep. It takes no parameters, returns no value and perform one task.
Custom Subroutine
A subroutine is simply a custom statement that you write yourself. You can write beep custom subroutne and call it to your VBScript to make it beep as many time as you want.
Comments and Documentation
Documenting and commenting your script is always beneficial for the future reference and also makes your script look tidy. This is a good practise to follow.
