         long   ModelVar;
         long   ModelOper;
         long   MaxVar;
         long   MaxNode;

PARAMETERS

              The ModelVar parameter must be a positive value.
       "system model oper xxx error !"
              The ModelOper parameter must be a positive value.
       "variable xxx out of range error !"
              The MaxVar parameter must be less than BDD_MAX_VAR.
