How can I display all of the contents of a single-dimension array?

There are a number of ways you can display the contents of a single-dimension array. Use a 'For ... Next' loop to iterate through each element in the array. You can find the lower and upper bounds of an array by using the LBound and UBound functions, respectively.

The following snippet of code displays each element of the array aFoo using a 'For ... Next' loop

'Create the aFoo array
Dim aFoo
aFoo = Array("Hello", "Aplus!", "How ", "are ", "you?"

Dim iLoop
For iLoop = LBound(aFoo) to UBound(aFoo)
Response.Write aFoo(iLoop) & "<BR>"
Next

The above code will produce the following output (when viewed through a browser)

Hello
Aplus!
How
are
you?

There is another way to display the contents of a single-dimension array. VBScript provides a join function that converts the contents of an array into a string using a specified delimiter between each element of the array in the string. To display each element of an array, followed by a <BR>, use the following code:

'Create the aFoo array
Dim aFoo
aFoo = Array("Hello", "Aplus!", "How ", "are ", "you?"

Response.Write join(aFoo, "<BR>")

This code will produce the exact same output as the code snippet we first examined, but it requires less code.
