Nature of problem:
Numerical evaluation of the associated Legendre polynomial PML(x).
Expansion of PML(x) in Chebyshev polynomials and evaluation of the coefficients by recurrence.
Ranges confined to 0<= x <=1, 0<= L <=250 and 0 <= M <= 10 with even values of M only.
The high speed storage requirement can be reduced by the user - the main contributing factor being array APO in COMMON CB8.
For the test case 1.27 s.
