RE: accessing weights in user routines

I agree with the Mario's remark

On the other hand, the reduction factor input as WHAT(2) of the LAM-BIAS
card and applying to the inelastic interaction length, is actually stored
in BIASIN(IJ), available in (PAPROP), being IJ the particle code (as
listed in the Chapter 5 of the manual)

Ciao
