     The notes in section 26.6.8 say that vpiLeftRange and
     vpiRightRange apply to variables when and only when
     vpiArray is TRUE (Note 5). Note 3 says that vpiArray
     is TRUE if and only if the variable handle references
     and array of variables. So a single variable (integer,
     time, or real) that is not part of an array does
     not have a vpiLeftRange or a vpiRightRange.
     
     But in this case, it is also an error to return a
     vpiLeftRange or vpiRightRange. These relations do
     not return a NULL handle for a non-array variable.
     
     Regards,
     Jim V.
