Constants
Constants are values which may be used but not changed by the program.
Defining Constants
In Apache OpenOffice Basic, use the keyword Const to declare a constant.
Const A = 10
You can also specify the constant type in the declaration:
Const B As Double = 10
Scope of Constants
Constants have the same scope as variables (see Scope and Life Span of Variables), but the syntax is slightly different. A Const definition in the module header is available to the code in that module. To make the definition available to other modules, add the Public keyword.
Public Const one As Integer = 1
