  We present preliminary measurements of the CP asymmetry parameters and CP
content in B0 --> K+K-K0L decays, with B0 --> phi K0L events excluded. In a
sample of 227 M B bar B pairs collected by the BaBar detector at the PEP-II B
Factory at SLAC, we find the CP parameters to be S = 0.07 +/- 0.28 (stat)
{+0.11} {-0.12} (syst)
  C = 0.54 +/- 0.22 (stat) {+0.08} {-0.09} (syst) where the first error is
statistical and the second is systematic. Estimating the fraction of CP-odd
final states from angular moments analysis in the K+K-K0S CP-conjugate final
state, f_{odd} (K+K-K0L) = 0.92 +/- 0.07 (stat) +/- 0.06 (syst) we determine
sin 2beta_{eff} = 0.09 +/- 0.33, (stat) {+0.13} {-0.14} (syst) +/- 0.10 (syst
CP-cont)
