Declaring Variables
Declaring variable is letting VB know about how we intend to
use the variable. For example, if you declare a variable as String, then it means you want to store
characters into it. Dim statement is
used to declare variables.
Dim variable [as datatype]
Variable is the
name of the variable and datatype is
the type of variable. If datatype is not given then variable is taken to be of
variant type.
Examples
Dim n as integer
Dim amount as long, discount as integer
Dim amount, totamount as
long
In the last example, only totamount is taken to be long and
amount is treated as variant type.
