ExcelBanter - Paste Array to .xls : All at once

I know it is a lot of code, but this function (ArrayToSheet) will put any
array in the sheet:

Is there a way to paste the entire array directly to a worksheet. Assume
the
array is unsorted, dynamically sized using Redim, and has 1mio values, and
can occupy all 256 columns and as many rows as required.

TIA!
