C-      Fetch information from next bank in ISAL linear structure
C-
C-   Inputs  :
C-     LSUP= supporting link, should be LISAE-IZISAL (or 0)
C-           to get information from first bank in linear structure
C-           and LISAL for preceding bank otherwise.
C-   Outputs :
C-     LISAL= structural link to ISAL providing information
C-     ID   = particle ID
C-     P(4) = 4-momentum (px, py, pz, E)
C-     TH   = theta
C-     PHI  = phi
C-     ETA  = eta (pseudo-rapidity)
