PROGRAM CBLAT2
*
* Test program for the COMPLEX Level 2 Blas.
*
* The program must be driven by a short data file. The first 17 records
* of the file are read using list-directed input, the last 17 records
* are read using the format ( A12, L2 ). An annotated example of a data
* file can be obtained by deleting the first 3 characters from the
* following 34 lines:
* 'CBLAT2.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.
* 2 0 TO TEST COLUMN-MAJOR, 1 TO TEST ROW-MAJOR, 2 TO TEST BOTH
* 16.0 THRESHOLD VALUE OF TEST RATIO
