+c      on the number of implied multiple subscripts.
+c      the subroutine is called once for each variate.

+c
+c n is the dimension of the current variable.
+c nspn is the spacing of consecutive data values

+c nseg*n*nspn is the total number of complex data values.
+c the sign of isn determines the sign of the complex

+c
+c if fft is called twice, with opposite signs on isn, an
