Variables in VB Script

VB Script Variables: Variable is nothing but we are allocating some space to the particular variable to store some information. In variables we are storing the information to that value.

A=10

Here A is Variable Name

In VB Script we have two types of Variables.

1) User defined Variables

2) Pre-defined Variables.

Variables: 

For example:  a= 1o, dim =10

                       Here a=variable name

                                 10=we are assigning one value to the particular variable.

1) User defined Variables: In user defined variable user will define the variable name.

For example:  a= 1o

                       Here a=variable name

                                 10=we are assigning one value to the particular variable.

 2) Pre-defined Variable: per-defined variable means Vb Script having default variables those variables are called Pre-defined.

For example:  dim= 1o

                       Here a=variable name

                       10=we are assigning one value to the particular variable.

In this example dim is a per-defined variable. We can’t use that variable as a user defined variable.
