Global keyword

Dimensions a variable or an array at the global level (that is, not within a subroutine or function), so that the variable and the array are valid in all libraries and modules for the current session.

Syntax:

Global VarName[(start To end)] [As VarType][, VarName2[(start To end)] [As VarType][,...]]

Example:

Global iGlobalVar As Integer
Sub ExampleGlobal
    iGlobalVar = iGlobalVar + 1
    MsgBox iGlobalVar
End Sub
