/*
--  Use Windows Explorer (Windows) or the 'cd' and 'pwd' commands 
--  (Unix/Linux) to navigate to the student files directory for this 
--  chapter.  Note and copy the full pathname to this directory, for use 
--  in the next exercise.
--
--  On Unix/Linux, use 'ls -ld' and the 'chmod' command to examine, and
--  if needed, change the permissions on this directory so that the
--  'oracle' account can read and write to it.  For example, if the path
--  is:
--    /home/student/o11pl/ch11
--  then:
--     ls -ld /home/student/o11pl/ch11
--     chmod 777 /home/student/o11pl/ch11
--  Be sure the intervening parent directories are also navigable by the
--  oracle account.  For example:
--     ls -ld /home/student
--     chmod 755 /home/student
--
--  On Windows, just make sure 'Everybody' has 'Change' or 'Full' access
--  on the directory.
