\fIJOB\fP 
.PP
.nf
          JOB is CHARACTER*1
          Specifies the type of backward transformation required:
          = 'N': do nothing, return immediately;
          = 'P': do backward transformation for permutation only;
          = 'S': do backward transformation for scaling only;
          = 'B': do backward transformations for both permutation and
                 scaling\&.
          JOB must be the same as the argument JOB supplied to CGEBAL\&.

          SIDE is CHARACTER*1
          = 'R':  V contains right eigenvectors;
