 DCHKAA is the main test program for the DOUBLE PRECISION LAPACK
 linear equation routines

 The program must be driven by a short data file\&. The first 15 records
 (not including the first comment  line) specify problem dimensions
 and program options using list-directed input\&. The remaining lines
 specify the LAPACK test paths and the number of matrix types to use
 in testing\&.  An annotated example of a data file can be obtained by
 deleting the first 3 characters from the following 40 lines:
