Excel Object Model: cell

The Excel object model doesn't have a distinct object for a cell. Rather, a cell is represented by a Range object that happens to be a 1x1 cell range.
A range that represents an arbitrary cell can be instantiated and accessed by giving the cell's address to the Range »constructor«:

'   ..\..\..\runVBAFilesInOffice.vbs -excel b3 -c Go
'

public sub Go() ' {

    range("b3").value = "This is the value of b3"

end sub ' }
