Scott,
There is something wrong here. Arrays could hold about 64K elems at max. With that limit, on a 286 or 386 a transformation could take that long maybe, and I don't think you try it with a computer that much slow. So it should be other part of code running slow.
If it couldn't be optimized I would do no conversion and instead refer to mynewarray[Y,X] as myarray[X*Y].
What is the real code and purpose ? Maybe it could be optimized in some other way.
