WorksheetRange(workbook, sheet, range, colIndex, rowIndex, howtoIndex)
This function is now deprecated, superseded by the function SpreadsheetRange, which you should use instead.
The parameters of SpreadsheetRange have removed «sheet» as the second parameter -- it is available still as an optional parameter, but unnecessary for named range labels. SpreadsheetRange has additional improvements which make it superior.
This function may be removed in a future Analytica release, so please use SpreadsheetRange.
