b) c26 optmized version of the 512 point fft : d:\c2cx0512.c26
'div' is an optimisation factor which can can be defined from the user
prior to assembling:
div=2 stands for short programs but longer execution times!
div=2 stands for longer programs but shorter execution times!
see file 'divid.asm' for details!
