The following tables list all the Visual Basic language keywords.

Reserved Keywords

The following keywords are reserved, which means you cannot use them as names for your programming elements such as variables or procedures. You can bypass this restriction by enclosing the name in brackets ([ ]). For more information, see "Escaped Names" in Declared Element Names.

Note

Using escaped names is not recommended, because it can make your code hard to read, and can lead to subtle errors that can be difficult to find.
