*  =============
*>
*> \verbatim
*>
*> CCHKAA is the main test program for the COMPLEX 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 42 lines:
*> Data file for testing COMPLEX LAPACK linear equation routines
*> 7                      Number of values of M
*> 0 1 2 3 5 10 16        Values of M (row dimension)
*> 7                      Number of values of N
*> 0 1 2 3 5 10 16        Values of N (column dimension)
*> 1                      Number of values of NRHS
*> 2                      Values of NRHS (number of right hand sides)
*> 5                      Number of values of NB
