     _P_a_t_h is the pathname of a directory.  _C_h_d_i_r causes this
     directory to become the current working directory, the
     starting point for path names not beginning with ``/''.
     _F_c_h_d_i_r causes the directory referenced by _f_d to become the
     current working directory, the starting point for path names
     not beginning with ``/''.
     In order for a directory to become the current directory, a
     process must have execute (search) access to the directory.
