*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> Test program for the COMPLEX Level 3 Blas.
*>
*> The program must be driven by a short data file. The first 14 records
*> of the file are read using list-directed input, the last 9 records
*> are read using the format ( A6, L2 ). An annotated example of a data
*> file can be obtained by deleting the first 3 characters from the
*> following 23 lines:
*> 'cblat3.out' NAME OF SUMMARY OUTPUT FILE
*> 6 UNIT NUMBER OF SUMMARY FILE
*> 'CBLAT3.SNAP' NAME OF SNAPSHOT OUTPUT FILE
*> -1 UNIT NUMBER OF SNAPSHOT FILE (NOT USED IF .LT. 0)
*> F LOGICAL FLAG, T TO REWIND SNAPSHOT FILE AFTER EACH RECORD.
*> F LOGICAL FLAG, T TO STOP ON FAILURES.
*> T LOGICAL FLAG, T TO TEST ERROR EXITS.
*> 16.0 THRESHOLD VALUE OF TEST RATIO
*> 6 NUMBER OF VALUES OF N
*> 0 1 2 3 5 9 VALUES OF N
*> 3 NUMBER OF VALUES OF ALPHA
*> (0.0,0.0) (1.0,0.0) (0.7,-0.9) VALUES OF ALPHA
*> 3 NUMBER OF VALUES OF BETA
*> (0.0,0.0) (1.0,0.0) (1.3,-1.1) VALUES OF BETA
*> CGEMM T PUT F FOR NO TEST. SAME COLUMNS.
*> CHEMM T PUT F FOR NO TEST. SAME COLUMNS.
*> CSYMM T PUT F FOR NO TEST. SAME COLUMNS.
*> CTRMM T PUT F FOR NO TEST. SAME COLUMNS.
*> CTRSM T PUT F FOR NO TEST. SAME COLUMNS.
*> CHERK T PUT F FOR NO TEST. SAME COLUMNS.
*> CSYRK T PUT F FOR NO TEST. SAME COLUMNS.
*> CHER2K T PUT F FOR NO TEST. SAME COLUMNS.
