Columns before rows

In cell addresses, the column position comes before the row position. (Both start with 0.) So, I hope these are right,
oSheet.getCellByPosition(1,3)
is equivalent to
oSheet.getCellRangeByName("B4")
To get ranges:
oRange = ThisComponent.NamedRanges.getByName("Jason")
oRange = oSheet.getCellRangeByPosition(0,0,1,3)
oRange = oSheet.getCellRangeByName("a1:b3")
These are equivalent, provided Jason is a1:b3.
temp = oCell.getSpreadSheet().getName
temp2 = oCell.CellAddress.Column
temp3 = oCell.CellAddress.Row
get the name of the spreadsheet that oCell is on, the column number, and the row number.
temp = oRange.getSpreadSheet().getName
doesn't work.
oSheet = oDoc.Sheets.getByName("Brian")
oSheet = oDoc.Sheets.getByIndex(1)
are equivalent, provided the 2nd sheet is named Brian.
