+ PROGRAM CBLAT2
+*
+* Test program for the COMPLEX Level 2 Blas.
+*
+* The program must be driven by a short data file. The first 18 records
+* of the file are read using list-directed input, the last 17 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 35 lines:
+* 'CBLAT2.SUMM' NAME OF SUMMARY OUTPUT FILE
