A VLIW instruction format is introduced having a set of control bits which identify subinstruction sharing conditions. The data storage system includes a primary storage device and a spare storage device. NanMmn+RrQqAl1-xExSiyOz where M represents zinc or a metal or metals from Group 1, Group 2, Group 3 or the lanthanide series of the periodic table, R is an A,\u03a9-dihalosubstituted paraffin such as 1,4-dibromobutane, Q is a neutral amine containing 5 or fewer carbon atoms such as 1-methylpyrrolidine and E is a framework element such as gallium. The device may combine the user data and incoming data, including through any combination of encoding or decoding processes. The real-time mode identification module together with the real-time decision and control logic determines, from the mode information, whether there is an undesirable oscillation in the electric power system and activates a remedial action. In a second arrangement the two persons and the interpreter are at separate locations and a three-way call is initiated after the appropriate interpreter has been selected from the database.
