Some times you want to assign more than one value to a single variable. Then you can create a variable
that can contain a series of values. This is called an array variable. The declaration of an array variable
uses parentheses ( ) following the variable name. In the following example, an array containing 3 elements
is declared:
dim names(2)
The number shown in the parentheses is 2. We start at zero so this array contains 3 elements. This is a
fixed-size array. You assign data to each of the elements of the array like this:
names(0) = "Tove"
names(1) = "Jani"
names(2) = "Ståle"
Similarly, the data can be retrieved from any element using an index into the particular array element you
want. Like this:
mother = names(0)
You can have up to 60 dimensions in an array. Multiple dimensions are declared by separating the numbers
in the parentheses with commas. Here we have a two-dimensional array consisting of 5 rows and 7
columns:
dim table(4, 6)
VBScript Procedures
We have two kinds of procedures: The Sub procedure and the Function procedure.
A Sub Procedure:
·
Is a series of statements, enclosed by the Sub and End Sub statements
·
Perform actions, but do not return a value
·
Can take arguments that are passed to it by a calling procedure
·
Without arguments, must include an empty set of parentheses ()
Sub mysub()
some statements
End Sub
The Function Procedure
·
Is a series of statements, enclosed by the Function and End Function statements
·
Perform actions, but can also return a value
·
Can take arguments that are passed to it by a calling procedure
·
Without arguments, must include an empty set of parentheses ()
·
Returns a value by assigning a value to its name
Function myfunction()
some statements
myfunction = some value
End Function
