kount = ILLZ( n, x, incx )
illz Integer. Number of non-negative values in a vector before the first negative value. The vector can be of type integer, logical, or real.
n Integer. The number of elements in the vector. x Integer, Logical, or Real vector. An input vector of length x. incx Integer. The increment between elements of vector x. For contiguous elements, incx = 1.
The function ILLZ returns the number of non-negative values before the first negative value in an array. It returns zero if the number of elements, n, is less than one.
