Built-in Constants

Also known as Intrinsic Constants.
In addition to literal and symbolic constants VBA also has a huge range of built-in constants.
Any built-in constants are examples of symbolic constants and generally start with the characters vb.

You should try and use the built-in constants rather than the values they represent because the value may change in future versions of VBA.
The constants are also more intuitive and easier to change at a later date, eg vbNewLine = Chr$(13).
