Scope and Life Span of Variables 22
A = A + 1
End Sub
Module B:
Sub Flop
A = A - 1
End Sub
The value of variable A is not changed by the Test function, but is increased by one in the
Flip function and decreased by one in the Flop function. Both of these changes to the
variable are global.
You can also use the keyword Public instead of Dim to declare a public domain variable:
Public A As Integer
A public domain variable is only available so long as the associated macro is executing and
then the variable is reset.
Global Variables
In terms of their function, global variables are similar to public domain variables, except
that their values are retained even after the associated macro has executed. Global
variables are declared in the header section of a module using the keyword Global:
Global A As Integer
Private Variables
Private variables are only available in the module in which they are defined. Use the
keyword Private to define the variable:
Private MyInteger As Integer
If several modules contain a Private variable with the same name, OpenOffice.org Basic
creates a different variable for each occurrence of the name. In the following example, both
module A and B have a Private variable called C. The Test function first sets the Private
variable in module A and then the Private variable in module B.
Module A:
Private C As Integer
