I'm not sure I understand exactly what you want to do, but I think the SPREAD function can help. It can create high dimension arrays by copying elements along a specific dimension. But, it's likely to be less efficient than DO loop notation. It would be easier to answer if you would give a DO loop based example of what you are doing.
