DESCRIPTION
It is assumed that RWORK and IWORK have initialized with the information required for SLLTI2: IWORK(1) = NEL IWORK(2) = Starting location of IEL in IWORK. IWORK(3) = Starting location of JEL in IWORK. IWORK(4) = Starting location of EL in RWORK. IWORK(5) = Starting location of DINV in RWORK. See the DESCRIPTION of SLLTI2 for details.
