CAP - Capacitor
      Initial Release

IND - Inductor
      Initial Release

RES - Resistor
      This is a modified version of the spice3 resistance model. This
      model supports different ac and dc values (ac=...). This changes
      are introduced by Serban Popescu. The "multiplicity factor" (m) 
      has been introduced. The "scale factor" has been introduced.
      
      *)Rework 11: The code has been modified to reflect spice parsing
        standard.
