L Maximum number of BFGS vectors.  

Comments

  1. /IMPL/NONLIN/2 should be defined.
  2. If L =0 or /IMPL/LBFGS/L is not defined, L = L_A is defined in /IMPL/NONLIN/N.

    When this keyword is defined, the new update vectors are accumulated over the old ones by sliding down the set of vectors loosing the oldest ones.
