      PROGRAM SBLAT3
*
*  Test program for the REAL             Level 3 Blas.
*
*  The program must be driven by a short data file. The first 13 records
*  of the file are read using list-directed input, the last 6 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 19 lines:
*  'SBLAT3.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
*  6                 NUMBER OF VALUES OF N
*  0 1 2 3 5 9       VALUES OF N
*  3                 NUMBER OF VALUES OF ALPHA
