ExcelBanter - R1C1 riddle

Yes, this is a quirk I came across a while back, and had to use a different
method to get around it. It appears that filling a range with a formula
automatically updates the cell reference much like entering a formula in a
cell then dragging it downward. I've never used the "=rc[1]" syntax but it
appears that the [1] means offset by one, and the automatic offset update of
filling the range is why the offset becomes 1, 3, 5.

I tried these statements stepping through the debugger to see how the
formulas are entered:

Private Sub Workbook_Open()

Range("A1:B2").ClearContents
Range("A1:A2").Formula = "=B1"

Range("A1:B2").ClearContents
Range("A1:A2").Formula = Array("=B1", "=D1")

Range("A1:B2").ClearContents
Range("A1:A2").FormulaArray = "=B1"

Range("A1:B2").ClearContents
Range("A1:A2").FormulaArray = Array("=B1", "=D1")

Range("A1:B2").ClearContents
Range("A1:B1").Formula = "=B1"

Range("A1:B2").ClearContents
Range("A1:B1").Formula = Array("=B1", "=D1")

Range("A1:B2").ClearContents
Range("A1:B1").FormulaArray = "=B1"

Range("A1:B2").ClearContents
Range("A1:B1").FormulaArray = Array("=B1", "=D1")

End Sub

It seems like the Array("", "") statement fills across the row, i.e. the
range("A1:A2") receives only the first element of the Array(), which is
subsequently copied (and offset) downward. Try it and see if you follow what
it does.

Can anyone explain why the first line of code is 'skipping rows' and
the second and third are not? What am I missing?

Range("a1.b10").Formula = Array("=rc[1]", "=""Row: ""&ROW()")

Range("a1.b10").FormulaArray = Array("=rc[1]", "=""Row: ""&ROW()")
Range("c1.c10").Formula = "=""Row: ""&row(rc[1])"

Checked in Excel 2000 and Excel XP.
