C C B contains the roots of all the B polynomials. C W1,W2,W3,WD,WW,WU are all working arrays. C PRDCT is either PRODP or PROD depending on whether the boundary C conditions in the M direction are periodic or not. C CPRDCT is either CPRODP or CPROD which are the complex versions C of PRODP and PROD. These are called in the event that some C of the roots of the B sub P polynomial are complex.
