subroutine cerrql ( character*3  path,
integer  nunit 
)

CERRQL

Purpose:
 CERRQL tests the error exits for the COMPLEX routines
 that use the QL decomposition of a general matrix.
Parameters
[in]PATH
          PATH is CHARACTER*3
          The LAPACK path name for the routines to be tested.
[in]NUNIT
          NUNIT is INTEGER
          The unit number for output.
