  JOB     CHARACTER*1
          Specifies the computation to be performed, as follows:
          = 'E': compute the eigenvalues only; A will not
                 necessarily be put into periodic Schur form;
          = 'S': put A into periodic Schur form, and return the
                 eigenvalues in ALPHAR, ALPHAI, BETA, and SCAL;
          = 'T': as JOB = 'S', but A is put into stand
