*> Each test path has a different set of inputs, but the data sets for
*> the driver routines xEV, xES, xVX, and xSX can be concatenated in a
*> single input file.  The first line of input should contain one of the
*> 3-character path names in columns 1-3.  The number of remaining lines
*> depends on what is found on the first line.
*>
*> The number of matrix types used in testing is often controllable from
*> the input file.  The number of matrix types for each path, and the
*> test routine that describes them, is as follows:
