Nature of problem:
Numerical evaluation of the associated Legendre polynomial PML(x).

Solution method:
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.

Unusual features:
The high speed storage requirement can be reduced by the user - the main contributing factor being array APO in COMMON CB8.

Running time:
For the test case 1.27 s.
