1.8 Enumerations

The Microsoft.VisualBasic namespace also defines a number of enumerations. Many of their members are functionally identical to almost identically named constants listed in the aforementioned Section 1.7.

1.8.4 ControlChars Class

Values representing a number of control characters are available as static read-only fields of the ControlChars class. They can be referenced just as enumerated members; for example:

Addr = "123 West St. & ControlChars.CrLf & _
