This is indeed the case.  I know it's a sloppy programming practice,
but it was the easiest way for me to interface with all my assembly
code that assumes the FFT data is at a fixed address.  Mprime actually
has 16MB of global variables.  Unless you are testing an exponent above
20,000,000 then you are only using a small fraction of the 16MB.

Best regards,
George
