What is the difference between Dim s As String and Dim s As [String]?

Question

What is the difference between:

Dim s As String

and

Dim s As [String]

Answer 1

There is no difference.

In VB, you can wrap an identifier in brackets to force it to be parsed as an identifier and not a keyword.

For example, you can write

Dim [If], [As], [Dim]

without any syntax errors.

The brackets have no effect other than indicating that the identifier isn't a keyword, so someVar and [someVar] are identical.
