The prefix MODIFICATION you did doesn't match the location
in the error message.

I believe "DATADIR" is an environment variable, and it is not
necessary to have an actual directory named DATADIR.

I.e., you could do

     v16->SetFilePrefix ("d:/ex/headsq/quarter");

and put your quarter.* data files in the d:\ex\headsq directory.
