NT stores data in <sysdrive>:\winnt\profiles\<username>\S_WORK.

The C function needs to be changed, as "the returned value of a C or Fortran 
function is lost,  so all  returned data  must  be passed back via the 
argument list.", see the programmer's manual.
void cubic(double *x, double *xcube) 
{
  *xcube=(*x)*(*x)*(*x);
  return;
}

Page 218, Example 10.4
The S-PLUS function needs to be changed to
cubic <- function (x)
{
  xcube <- 0
  the.cube <- .C ("cubic", as.double(x), as.double(xcube))
  xcube <- the.cube[[2]]
  return (xcube)
