      INTEGER MAXVEANCLASSES
      PARAMETER (MAXVEANCLASSES = 10)
C
C arrays that hold vectorangle info
C vectassndx tells ending index of the vect_x arrays (below)
C for each class.
C vectforces holds k1 and k2 for each class
C vectclasstypes holds the type of each class
C
C these are small enough not to bother with the heap.
