!> CCHKEC tests eigen- condition estimation routines
!>        CTRSYL, CTRSYL3, CTREXC, CTRSNA, CTRSEN
!>
!> In all cases, the routine runs through a fixed set of numerical
!> examples, subjects them to various tests, and compares the test
!> results to a threshold THRESH. In addition, CTRSNA and CTRSEN are
!> tested by reading in precomputed examples from a file (on input unit
!> NIN).  Output is written to output unit NOUT.
!> 

THRESH

!>          THRESH is REAL
!>          Threshold for residual tests.  A computed test ratio passes
!>          the threshold if it is less than THRESH.
!> 

TSTERR

!>          TSTERR is LOGICAL
!>          Flag that indicates whether error exits are to be tested.
!> 

NIN

!>          NIN is INTEGER
!>          The logical unit number for input.
!> 

NOUT

!>          NOUT is INTEGER
!>          The logical unit number for output.
