    C***DESCRIPTION
    C
    C BESKS computes a sequence of modified Bessel functions of the third
    C kind of order XNU + I at X, where X .GT. 0, XNU lies in (-1,1),
    C and I = 0, 1, ... , NIN - 1, if NIN is positive and I = 0, 1, ... ,
    C NIN + 1, if NIN is negative.  On return, the vector BK(.) Contains
    C the results at X for order starting at XNU.
